Abstract
The Stueckelberg formulation for transition probabilities is utilized to explain perturbation effects observed in elastic differential cross-section measurements. The model based on a competing trajectory concept implies oscillating cross sections for all inelastic processes occurring by means of a curve crossing mechanism. Variations are made in the slopes of two crossing potential-energy curves to determine the effect on the cross section. The model gives qualitative agreement with experiment, but definitive tests must await more accurate potential-energy curves.Keywords
