Contribution
It presents a complete Glauber theory formalism and a second-order approximation, along with an assessment of a simplified potential approximation's accuracy.
Findings
The second-order approximation improves scattering predictions.
The potential approximation's accuracy is quantitatively evaluated.
The formalism extends existing Glauber theory for elementary atom scattering.
Abstract
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.
