Progress in Impulse Approach Research

Abstract

This report entails the progress made during the first contract year in the research of Impulse Approach (IA) modeling. The IA technique was successfully applied to the Ar-CsF scattering system with results that compared favorably with observations. Limitations and discrepancies were also found in the treatment of other scattering systems which were attributed to the confinement of the IA method to the single collision T matrix. Work is at the present progressing on extending the approach to the double collision T Matrix. The Distorted Wave Impulse Approach (DWIA) is also being developed to model observed distributions of rotational transitional probabilities of the Li(+)-N sub 2 scattering system.
