The semi-relativistic scattering states of the two-body spinless Salpeter equation with the Varshni potential model

In this present work, the scattering state solutions of the Spinless Salpeter equation with the Varshni potential model were investigated. The approximate scattering phase shift, normalization constant, bound state energy, wave number and wave function in the asymptotic region were obtained. The behaviour of the phase shift with the two-body mass index {\eta} were discussed and presented.
