The scattering phase shifts of the Hulthén-type potential plus Yukawa potential
arXiv:1604.03618
Abstract
With the aid of an improved short-range approximation, the bound state energies and the scattering phase shifts for a Hulthén- type potential plus Yukawa potential are calculated within the framework of Nikiforov-Uvarov and standard methods, respectively. Our numerical calculations show that the presence of Yukawa potential has a significant influence on bound state energies and the wave number-dependent phase shifts for any arbitrary values of the screening parameter α and angular momentum l.
