Accurate calculation of low energy scattering phase shifts of charged particles in a harmonic oscillator trap

Year: 2024

Type: article

Abstract: Considering the elastic scattering of two charged particles, we present two methods for numerically solving the generalized Coulomb-corrected BERW formula with high accuracy across the entire energy spectrum . We illustrate these methods using p − α scattering, employing a phenomenological p − α short-range interaction. Our results reproduce the phase shifts computed with the Numerov method for all l = 0 and l = 1 channels. We also provide full access to the Python script used to obtain these results, which can be readily applied to a wide range of core-fragment scattering problems in nuclear and atomic physics .
