Phase function method, Poschl-Teller plus spin-orbit interaction, scattering phase shifts, nucleon-nucleon systemsAbstract
Scattering phase shifts for quantum mechanical potential scattering can be derived directly from the scattering amplitude, bypassing the need to solve the Schrödinger equation explicitly. This can be achieved by numerically integrating the phase equation from the origin to the asymptotic limit. The Phase Function Method (PFM) is considered an effective approach for computing scattering phase shifts in quantum mechanics. The Phase Function Method (PFM) is applied to analyze the Pöschl–Teller potential along with spin-orbit interactions. The strategy includes employing a five-parameter potential model to fit the calculated scattering phase shift curves to the established data for elastic scattering phase shifts. Numerical scattering phase shifts for nucleon-nucleon systems align well with prior research results.
