Hamiltonian hierarchy and the Hulthen potential

We deal with the Hamiltonian hierarchy problem of the Hulthen potential wit hin the frame of the supersymmetric quantum mechanics and find that the ass ociated supersymmetric partner potentials simulate the effect of the centri fugal barrier. Incorporating the supersymmetric solutions and using the fir st-order perturbation theory we obtain an expression for the energy levels of the Hulthen potential which gives satisfactory values for the non-zero a ngular momentum states.
