Measurements Of Deuteron Threshold Electrodisintegration: A Probe Of Short-Range Meson Exchange, K S. Lee, W Schmitt, H Baghaei, S Churchwell, R S. Hicks, R A. Miskimen, Gerald Alvin Peterson, K Wang Nov 1991

Measurements Of Deuteron Threshold Electrodisintegration: A Probe Of Short-Range Meson Exchange, K S. Lee, W Schmitt, H Baghaei, S Churchwell, R S. Hicks, R A. Miskimen, Gerald Alvin Peterson, K Wang

Gerald Alvin Peterson

The threshold electrodisintegration of the deuteron was measured with good energy resolution to a maximum four-momentum transfer squared of 42 fm-2. The data are compared with meson exchange calculations that show sensitivity to the choice of exchange-current form factor, the nucleon electromagnetic form factors, and the nucleon-nucleon potential. While conventional theories can give a reasonable description of the data, comparison of the data with quark cluster calculations shows poor agreement.


Elastic Magnetic Electron Scattering From ' C At Q2= 1 Gev2/C, R A. Miskimen, H Baghaei, M Frodyma, R S. Hicks, K S. Lee, Gerald Alvin Peterson Oct 1991

Elastic Magnetic Electron Scattering From ' C At Q2= 1 Gev2/C, R A. Miskimen, H Baghaei, M Frodyma, R S. Hicks, K S. Lee, Gerald Alvin Peterson

Gerald Alvin Peterson

Electron scattering from C was measured at a momentum transfer of 5.08 fm . No electron events were observed in the vicinity of the elastic peak, giving an upper limit for the elastic cross section of 1.2 x 10 cm /sr with a confidence level of 90%. At this momentum transfer, the square of the elastic M1 form factor apparently continues to fall exponentially with q. Comparison of the data with shell-model calculations indicates that admixtures of 2hu configurations in the C ground state cannot entirely explain the high-q enhancement of the Ml form factor relative to 1p-shell calculations.


A Language-Independent Garbage Collector Toolkit, Richard L. Hudson Sep 1991

A Language-Independent Garbage Collector Toolkit, Richard L. Hudson

Computer Science Department Faculty Publication Series

We describe a memory management toolkit for language implementors. It offers efficient and flexible generation scavenging garbage collection. In addition to providing a core of languageindependent algorithms and data structures, the toolkit includes auxiliary components that ease implementation of garbage collection for programming languages. We have detailed designs for Smalltalk and Modula-3 and are confident the toolkit can be used with a wide variety of languages. The toolkit approach is itself novel, and our design includes a number of additional innovations in flexibility, efficiency, accuracy, and cooperation between the compiler and the collector.


Two Kinds Of Training Information For Evaluation Function Learning, Paul Utgoff Jul 1991

Two Kinds Of Training Information For Evaluation Function Learning, Paul Utgoff

Computer Science Department Faculty Publication Series

This paper identifies two fundamentally different kinds of training information for learning search control in terms of an evaluation function. Each kind of training information suggests its own set of methods for learning an evaluation function. The paper shows that one can integrate the methods and learn simultaneously from both kinds of information.

Longitudinal Nmr Relaxation Of Degenerate 2-D 3he In 4he Films, Robert Hallock, D. T. Sprague, N. Alikacem Jan 1991

Longitudinal Nmr Relaxation Of Degenerate 2-D 3he In 4he Films, Robert Hallock, D. T. Sprague, N. Alikacem

Robert Hallock

The NMR spin-lattice relaxation time T1 of a degenerate submonolayer coverage of 3He in a thin adsorbed 4He film has been measured. As a function of 4He coverage, T1 exhibits a maximum and undergoes a change in temperature dependence at a coverage near that of the superfluid transition in the underlying 4He film. Two relaxation mechanisms contribute to the observed T1.


Linear Tc Depression In Mg Doped Yba2cu3o7-X, Robert Hallock, W. M. Tiernan Jan 1991

Linear Tc Depression In Mg Doped Yba2cu3o7-X, Robert Hallock, W. M. Tiernan

Robert Hallock

We report resistivity-versus-temperature measurements performed on polycrystalline pellets of YBa2(Cu1-xMgx)3O7-δ made using the polymer-metal-complex precursor method. Tc was found to decrease linearly with increasing Mg doping in the range x=8.6×10-4 to 8.6×10-3 with slope -1400 K/x; the normal-state resistivity and the superconducting transition width showed little or no change. Mg was found to have a maximum solubility in YBa2(Cu1-xMgx)3O7-δ of x~=9×10-3.
