A complete version of the Glauber theory for elementary atom-target atom scattering and its approximations

摘要

A general formalism of the Glauber theory for elementary atom (EA)-target atom (TA) scattering is developed. A second-order approximation of its complete version is considered in the framework of the optical-model perturbative approach. A 'potential' approximation of a second-order optical model is formulated neglecting the excitation effects of the TA. Its accuracy is evaluated within the second-order approximation for the complete version of the Glauber EA-TA scattering theory.
