EXACT QUANTUM AND SEMICLASSICAL CALCULATION OF POSITIONS AND RESIDUES OF REGGE-POLES FOR INTERATOMIC POTENTIALS

Abstract:

Semiclassical and exact quantum methods have been used to calculate the positions and residues of Regge poles for two interatomic potentials. A Lennard-Jones (6,4) potential with parameters approximating H+-Ar collisions and a Lennard-Jones (12,6) potential with parameters approximating the elastic scattering of K by HBr have been used. There is good agreement between the semiclassical and quantum calculations both for the pole positions and modulus and phase of the residues. Some properties ...
