Experimental and Theoretical Studies of IonMolecule Scattering.
Abstract
Incomplete total cross sections were measured for K(+) scattered by He, Ne, Ar, Kr, Xe, N2, CO, CO2, CH4, C2H4, C2H6, CF4 and SF6.. Measurements were carried out in the range E theta sub R = 2  200 eV deg, where E is the energy of the K(+) beam and theta R is the resolution angle of the apparatus. Methods are developed for the spherically symmetric systems to calculate the classical incomplete total cross section as a function of the reduced resolution angle, Tau sub R = E theta sub R. Computed cross sections are compared to the experimental results for the rare gases and best fit potentials are determined in the region of the attractive well. Total cross sections were calculated for a model potential that included dipole and quadrupole contributions. The effects of these anisotropies on the total cross section are discussed. A Monte Carlo method for calculating classical differential cross sections for known potentials is developed.
