摘要：
We determine exact solutions of the time-independent Schrodinger equation for the Rosen-Morse type potential by using the Nikiforov-Uvarov method. This method allows us to write the eigenfunctions of the Schrodinger equation as the product of two simpler functions in a constructive way. The resolution of this problem is used to show that the kinks of the non-linear Klein-Gordon equation with ������2 ������+2 type potentials are stable. We also derive the orthogonality and completeness relations satisfied by the set of eigenfunctions, which are useful in the description of the dynamics of kinks under perturbations or interacting with antikinks.
