Analysis of Cross Sections and Analyzing Powers in the \(p\)–He\(³\) Elastic Scattering Using a Spin-Dependent Modified Kratzer Potential

This study explores the elastic scattering of charged hadronic system through a new approximation scheme for the effective potential. The Phase Function Method (PFM) is employed to examine the scattering phase shifts in the \(p\)–He\(³\) system, where a modified Kratzer potential is enhanced by electromagnetic interactions and spin–orbit coupling. A six-parameter potential model is developed and optimized to match the calculated scattering phase shifts, differential cross-sections, and proton analyzing power curves with experimental data for the \(p\)–He\(³\) system. The results show strong consistency with experimental measurements and previous theoretical predictions, affirming the accuracy and utility of the proposed method in analyzing scattering phenomena within this system.
