Electromagnetic Dissociation of Nuclei in Heavy-Ion Collisions
C. J. Benesh, J. L. Friar
Large discrepancies have been observed between measured Electromagnetic Dissociation(ED) cross sections and the predictions of the semiclassical Weizäcker-Williams-Fermi(WWF) metho…
Coherent States and Squeezed States, Supercoherent States and Supersqueezed States
Michael Martin Nieto
This article reports on a program to obtain and understand coherent states for general systems. Most recently this has included supersymmetric systems. A byproduct of this work has…
Microscopic approach to pion-nucleus dynamics
C. M. Chen, D. J. Ernst, M. B. Johnson
Elastic scattering of pions from finite nuclei is investigated utilizing a contemporary, momentum--space first--order optical potential combined with microscopic estimates of secon…
High-energy pion-nucleus elastic scattering
C. M. Chen, D. J. Ernst, M. B. Johnson
We investigate theoretical approaches to pion--nucleus elastic scattering at high energies (300 1 GeV). A ``model--exact'' calculation of the lowest--order microscopic…
Statistical Mechanics of Kinks in (1+1)-Dimensions
Francis J. Alexander, Salman Habib
We investigate the thermal equilibrium properties of kinks in a classical field theory in dimensions. The distribution function, kink density, and correlation function…
Length-scale competition in the damped sine-Gordon chain
David Cai, A. R. Bishop, Angel Sanchez
It is shown that there are two different regimes for the damped sine-Gordon chain driven by the spatio-temporal periodic force with a flat initial condition. F…
