Perturbation Theory In A Strong-Interaction Regime With Application To 4d-Subshell Spectra Of Ba And La, Göran Wendin, Anthony F. Starace
Perturbation Theory In A Strong-Interaction Regime With Application To 4d-Subshell Spectra Of Ba And La, Göran Wendin, Anthony F. Starace
Anthony F. Starace Publications
We investigate the behavior of a bound electron–hole excitation in an energy region where the response of the system is highly resonant and shows strong collective behavior. Formulae for calculating discrete energy levels and wavefunctions are presented for the case where the perturbation is strong enough to change the nodal structure of the perturbed wavefunctions relative to that of the unperturbed wavefunctions. This change in nodal structure requires a renaming of the associated atomic states. Neglect of such renaming is shown to have been at the root of a recent controversy between differing interpretations, based on alternative calculational procedures, of …

An Illustrative Model Describing The Refraction Of Long Water Waves By A Circular Island, Gregory A. Kriegsmann
An Illustrative Model Describing The Refraction Of Long Water Waves By A Circular Island, Gregory A. Kriegsmann
Department of Mathematics: Faculty Publications
The refraction of small shallow water waves by an idealized island is studied in this paper. The island's shoal is modeled by a quartic polynomial in the radial variable. This particular model allows the explicit construction of the rays (wave orthogonals) and the determination of several important features of the wave motion. The various shortcomings of the particular profile are discussed.

Radiobiological Aspects Of Supralinear Photographic Emulsions, Robert Katz, Edward C. Pennington
Radiobiological Aspects Of Supralinear Photographic Emulsions, Robert Katz, Edward C. Pennington
Robert Katz Publications
Abstract Nuclear emulsions of the Ilford K series, exposed to X-rays from 15 to 150 kVp and systematically underdeveloped, exhibit supralinear blackness-exposure curves ranging from 1- to 4-hit in character, and whose shape is the same at all excitation voltages. Processing can be so adjusted that the curve shape is well represented by the model, and matches an experimental dose-response curve obtained with hamster cells after irradiation with gamma rays. The effective grain size of these emulsions is 1.3 μm when normalized to unit density material for comparison with the radiation-sensitive elements of biological cells. With fractionated exposures, response …

Higher Education Learning Project (Physics) Books, Robert Fuller
Robert G. Fuller Publications
The books in this small collection of paperbacks deal with many of the issues confronting physicists who teach undergraduates. These books are the result of several physicist- years of studying various aspects of teaching in undergraduate physics programs in the United Kingdom. Each book includes references to related books and articles. I think that these books make an essential contribution to the literature about teaching physics at the university level. For too long many of the physics departments that I know have acted as if the only way to evaluate teaching was to give a multiple-choice questionnaire to students at …
High Let Constraints On Low Let Survival, Robert Katz
High Let Constraints On Low Let Survival, Robert Katz
Robert Katz Publications
Survival curves for biological cells irradiated with gamma rays (and other low LET radiations) cannot be properly interpreted without examining the implications of these interpretations for high LET radiations. The theory of RBE demands that the RBE of any high LET radiation field is at most one when the probability for cell killing as a function of the absorbed dose of gamma rays is linear or sublinear, for homogeneous samples whose radiosensitivity parameters are not altered during the irradiation. A contrary experimental finding strongly suggests that the experimental sample is heterogeneous. Violation of this constraint is not unusual where the …

Effect Of Random Anisotropy On Magnetic Properties Of Amorphous Systems, J.D. Patterson, G.R. Gruzalski, David J. Sellmyer
David Sellmyer Publications
We consider the random anisotropy model for amorphous magnetism by making a local-mean-field approximation (LMFA) on arrays of spin-one particles. Hysteresis loops and the temperature (T) dependence of several thermodynamic quantities are presented for various values of the ratio of the strength of the exchange (J) to the strength of the uniaxial anisotropy (D). Using the LMFA limits us to systems with a small number (N) of spins, of which we explicitly consider N=64, 216, and 1000. We assume periodic boundary conditions on a system with N1/3 spins along …

Graphical Approach To The Spin-Orbit Interaction, Keh-Ning Huang , Anthony F. Starace
Anthony F. Starace Publications
We derive a new form for the matrix element of the two-particle mutual spin-orbit interaction in the Breit-Pauli approximation. The complexity of standard tensor-operator expansion techniques is obviated by suitably decomposing the mutual spin-orbit interaction into products of spin and orbital angular-momentum operators, whose matrix elements in the lmisms scheme are obtained in a straightforward manner. Graphical representations are given for both the one- and two-particle spin-orbit interactions, thereby permitting the analytical evaluation by graphical techniques of the spin-orbit interaction between arbitrary configurations in any coupling scheme. The graphical procedure for evaluating these matrix elements is demonstrated …

Representation Of Ab Initio Energy Surfaces By Analytic Functions, R.L. Vance, Gordon A. Gallup
Representation Of Ab Initio Energy Surfaces By Analytic Functions, R.L. Vance, Gordon A. Gallup
Gordon Gallup Publications
A method for the analytical representation of ab initio energy surface results is described. For a three-atom surface, the potential function is written as a sum of atomic, two-body, and three-body terms. This allows an easy fitting of the whole surface, including the dissociated and united atom limits. The theory is applied to an H3 surface of limited accuracy calculated for these purposes. Comparisons are made, where possible, with more accurate calculations. Extensions to surfaces involving four or more atoms are also discussed.
