Abstract: We investigate non-s bound states in a screen Coulomb potential V(r)=-λ exp(-αr)/r,with different algorithms.The Schrödinger equation is solved using 4-step Runge-Kutta Method and Monte-Carlo approach.We analyzed errors of the MCH method.The energy spectrum and wave function in ground state and excited state agree well with those of 4-step Runge-Kutta method.

Key words: screen Coulomb potential, Monte Carlo Hamiltonian, effective potential
