The G-Factor Of The 7/2+ 1264.4 Kev Level In 97zr, Z. Berant, R. L. Gill, M. H. Rafailovich, R. E. Chrien, J. C. Hill, F. K. Wohn, R. F. Petry, C. Chung, Graham F. Peaslee, M. Mohsen

Faculty Publications

The g-factor of the level in 97Zr has been measured using the time-differential perturbed angular correlation method. The resultant g-factor, g=+0.39(4) is consistent with the simple shell model prediction for a if neutron, assuming gs=gsfree. This is in contrastrast to the measured in 115Sn, 121Te, 125,127Xe where consistency is obtained with theoretical calculation by assuming gs≈0.7 gsfree and is seen as another confirmation of quasi-shell closure at 96Zr.

G-Factor Measurements Of 41+ States In The N=82 Isotones 136xe And 138ba, Z. Berant, A. Wolf, John C. Hill, F. K. Wohn, R. L. Gill, H. Mach, M. Rafailovich, H. Kruse, B. H. Wildenthal, Graham F. Peaslee, A. Aprahamian, J. Goulden, C. Chung

The g factors for the 4+1 states in Xe136 and Ba138 were measured using the method of time-integral perturbed angular correlation. The levels of interest were populated by the decay of mass-separated I136 and Cs138. g factors of 0.80±0.15 and 0.80±0.14 were measured for the 4+1 states in Xe136 and Ba138, respectively. The above results, along with those for the g factors in the 4+1 state in Ce140 and the 6+1 states in Te134 and Ba138, are well described by a shell-model calculation in which the effective elemental proton g factors are g’l=1.12 and g’s=4.12.

Multiplicities For Evaporative 4he Emission In Heavy Ion Reactions: Relationships To Spin And Lifetime Expectancy Of The Composite Nucleus, N. N. Ajitanand, John M. Alexander, H. Delagrange, E. Duek, D. Ø. Eriksen, D. Guerreau, Morton Kaplan, M. Kildir, L. Kowalski, R. Lacey, D. Logan, D. J. Moses, Graham F. Peaslee, Louis C. Vaz, M. S. Zisman

Faculty Publications

Multiplicities are compared for4He evaporation in reactions of40Ar and56Fe projectiles (8.5 MeV/u) with withnatAg and238U targets. Coincidence requirements involving fusion-fission and projectile-like fragments have been used to select separate entrance-channel spin zones. Evaporation-like4He emission from the composite nuclei is shown to be large for mean spins ≦100ℏ, and to decrease dramatically with increasing spin. Coincidence measurements between two4He particles have also been studied for40Ar+natAg. This requirement is shown to select reactions that lead to evaporation residues and therefore to a zone of relatively low spin. The shapes of the4He spectra provide an interesting probe of the mechanism and also of …

Gamma-Gamma Angular Correlation Studies For 142ce, A. Wolf, C. Chung, W. B. Walters, R. L. Gill, M. Shmid, R. E. Chrien, Graham F. Peaslee

Faculty Publications

Gamma-gamma angular correlations for several cascades in 142Ce were measured using a four-detector system. In a recent publication the level at 1219 keV was assigned 22+ in contradiction to a previous assignment of 41+. This makes 142Ce completely different from any known nucleus in the same region. It is shown, however, that this level is, in fact, completely consistent with 4+ and is in agreement with systematics.

Magnetic Moments Of 21+ States As A Probe Of The Effective Proton Boson Number Near The Z = 64 Subshell, A. Wolf, Z. Berant, D. D. Warner, R. L. Gill, M. Shmid, R. E. Chrien, Graham F. Peaslee, H. Yamamoto, John C. Hill, F. K. Wohn, C. Chung, W. B. Walters

Faculty Publications

The g-factors of the 21+ states in 144, 146Ba have been measured using the perturbed angular correlation method. The results are combined with existing experimental data for the neutron-rich Nd, Sm and Gd isotopes and discussed in the framework of the neutron proton interacting boson model. It is shown that the assumption of a drastic change in the effective proton boson number around N = 88, proposed in an earlier study, allows all the results to be explained in a simple framework involving constant values of the boson g-factors.

A Four-Detector System For Γ - Γ Angular Correlation Studies, A. Wolf, C. Chung, W. B. Walters, Graham Peaslee, R. L. Gill, M. Shmid, V. Manzella, E. Meier, M. L. Stellts, H. I. Liou, R. E. Chrien, D. S. Brenner

Faculty Publications

A multiple detector system for γ - γ coincidence and angular correlation measurements is described. The system consists of four large coaxial Ge detectors set at fixed positions, enabling the measurement of γ - γ coincidences between any pair. Thus, six distinct angles are measured simultaneously. The performance of the system was studied with a 152Eu source. An application for γ - γ correlation studies in 146Ce is described. Systematic errors, if present, are shown to be less than 0.03 and 0.05 for A2 and A4, respectively. The extension of this system to more than four detectors is straightforward.

Successional Trends In An Ungrazed, Arid Grassland Over A Decade, Edgar F. Kleiner

Canyonlands Research Bibliography

A study has been made of the vegetational condition of a formerly grazed area, Chesler Park, in Canyonlands National Park. A comparison was made with the same area 10 years earlier. The 10-year successional changes are also compared to baseline data of 10 years earlier from Virginia Park, an adjacent ungrazed area. Because of inaccessibility and long isolation from disturbances, Virginia Park is presumed to be in climax condition and is the control for this study. Chesler Park shows a successional trend after 10 years toward the vegetational condition of Virginia Park. This is exemplified, with only one major exception …

Eleven Year Vegetational Comparison In An Arid Grassland, Edgar F. Kleiner

Canyonlands Research Bibliography

A study has been made of the vegetational condition of two graben valleys in Canyonlands National Park. The sites, formerly subjected to relatively heavy grazing pressure, were originally investigated in 1970 and analyzed again in 1981, providing an eleven-year record of succession. Comparisons are made to successional trends noted in related studies of disturbed and pristine areas. The graben valleys, with few exceptions, show a successional trend over eleven years toward the climax vegetational condition of an area that has never been disturbed.

Factors Influencing Development Of Cryptogamic Soil Crusts In Utah Deserts, David C. Anderson, Kimball T. Harper, Ralph C. Holmgren

Canyonlands Research Bibliography

The relation of some physical and chemical soil characteristics to cryptogamic crust development was determined from sites in semidesert regions of southern Utah. The effects of grazing on cryptogamic crust development also was examined. Electrical conductivity, percentage silt, and soil phosphorus were found to be correlated with well-developed cryptogamic crusts. Both total cryptogamic cover and the number of cryptogamic species decreased under grazing pressure. The management of rangelands, especially in arid regions, would be strengthened by understanding the role of cryptogamic crusts and considering them in range management decisions.

Occurrence Of Four Major Perennial Grasses In Relation To Edaphic Factors In A Pristine Community, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

The ecology and phytosociology of a virgin grassland community (Virginia Park, Canyonlands National Park, Utah) have been investigated. Based on the use of C √ó F index, Hilaria jamesii and Stipa comata are the most abundant of the four major perennial grasses. Oryzopsis hymenoides and Sporobolus cryptandrus are less abundant in decreasing order. The sites dominated by Hilaria are characterized by soils with finer texture, slightly warmer average temperature and higher surface K+ and organic matter compared to sites dominated by Stipa comata. In addition, frequency of both vascular and cryptogamic species is greater on sites dominated by Hilaria.

Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper

Canyonlands Research Bibliography

Sixty uniformly distributed stands in adjacent areas, 40 in Virginia Park (virgin) and 20 in Chesler Park (grazed), were analyzed. Cryptogamic and vascular species were recorded; cover was analyzed by the point sampling method, and frequency by means of 25 quadrats (each 0.125 m^2) per stand. The prevalent species (26 in Virginia, 23 in Chesler) were selected on the basis of a constancy-times-frequency index. Interspecific association patterns were determined by means of simple procedures based on quadrat frequency values for each species in the individual stands. Major environmental variables were recorded at each stand, and soil samples from four depths …

The Colorado Plateau, Robert Durrenberger

Canyonlands Research Bibliography

The Colorado Plateau was one of the last areas in the United States to be developed economically. Before the 1880s it was virtually empty except for Indians. Today the vast scenic and energy resources of the area are under development, and projections for future development are frightening. Problems of land use management are directly related to the fragmented nature of landholdings. Present methods of consolidation are inadequate, and new approaches to the organization of space must be devised if further degradation of the environment is to be prevented.

A Working Plan For The Woodlands Of The New Haven Water Company; Prepared After Five Years Of Forest Practice, 1908 To 1912, Ralph C. Hawley

Yale School of the Environment Bulletin Series

Soon after the establishment of the Yale Forest School in 1900, the necessity developed for finding forest lands near the city of NewHaven upon which to conduct field work. It was found that many of the most accessible and best timbered tracts were owned by the New Haven Water Company....about 250 acres near the Maltby Lakes were placed under the management of the Yale Forest School. ...a written plan is desirable. The plan is divided into two parts: the first, descriptive of present conditions and passt accomplishments; the second, treating of the policy to be pursued.
