Exact solutions of the Spinless-Salpeter equation under Kink-Like potential

The exact solution of Spinless-Salpeter equation （SSE） in the presence of Kink-Like potential is in-vestigated. By using the basic concepts of the supersyrnmetric quantum mechanics （SUSYQM） formalism and the functional analysis method, we have obtained the bound state solutions in the closed form and the eigenfunctions of the system are reported in the term of hypergeometric function. We have also reported some numerical results.
