Abstract
A combination of separable local and non-local interactions, in conjunction with a central-type spin-orbit interaction, is exploited through the Taylor-series expansion method to develop an equivalent velocity-dependent potential. This interaction model is utilized to investigate the elastic scattering phase shift in the alpha-nucleon system. The incorporation of the spin-orbit interaction improves the results significantly in comparison to the previous observation. Our findings exhibit a high degree of consistency with standard data without any additional adjustments. Remarkably, there is a good agreement between the differential cross section that is calculated from the phase shift and the experimental values.
