Homogeneous cooling state of a low-density granular flow
(American Physical Society, 1996)
The homogeneous cooling state of a granular flow of smooth spherical particles described by the Boltzmann equation is investigated by means of the direct simulation Monte Carlo method. The velocity moments and also the ...

Relativistic Quantum Scattering of High Energy Fermions in the Presence of Phase Transition
(Elsevier, 1996)
We study the high energy behaviour of fermions hitting a general wall caused by a first-order phase transition. The wall profile is introduced through a general analytic function. The reflection coefficient is computed in ...

On the relation between algebraic and configuration space calculations of molecular vibrations
(Elsevier, 1996-03)
The relation between algebraic and traditional calculations of molecular vibrations is investigated. An explicit connection between interactions in configuration space and the corresponding algebraic interactions is established.

Selective nuclear transparency induced by chaotic scattering
(American Physical Society, 1996-10-28)
We investigate the effects of nuclear absorption on the population of intrinsic vibrational states in scattering processes involving heavy ions. It is found that at the classical level the removal of flux assumes a ...

A general algebraic model for molecular vibrational spectroscopy
(Elsevier, 1996)
We introduce the anharmonic oscillator symmetry model to describe vibrational excitations in molecular systems exhibiting a high degree of symmetry. A systematic procedure is proposed to establish the relation between the ...

Low-temperature relaxation in the one-dimensional Ising model
(American Physical Society, 1996)
The decay of the spin-spin time correlation functions in a one-dimensional Ising model with Glauber dynamics is studied. In the low-temperature limit, an asymptotically valid continuous space equation is derived. It is a ...

Local icosahedral structures in binary-alloy clusters from molecular-dynamics simulation
(American Physical Society, 1996)
We investigate the structure of 13-particle clusters in binary alloys for various size ratios and different concentrations via molecular-dynamics simulation. Our goal is to predict which systems are likely to form local ...

Dynamic effective potential for α-particle bound and quasibound states
(American Physical Society, 1996-09-01)
We exploit analytic properties of the optical potential for elastic scattering of α particles on nuclei to extract information on the effective interaction that should be used to describe the motion of a cluster of two ...

Path Integral Solution of the Kramers Problem
(American Physical Society, 1996-12-30)
An iterative method to generate a discrete path integral solution of the Kramers problem is presented. It is based on a straightforward derivation of the functional formalism from the underlying Langevin equations. The ...
