Sažetak
We report here that the Renormalized Numerov (RN) method, commonly used to solve a system of coupled differential eigenvalue equations (CDEE), has an unexpected convergence behaviour as the step size is decreased. Furthermore, incorporation of the appropriate asymptotic behaviour of the wave function, in place of a sharp cut off, enhances the binding energy by about 10%. As an illustration, we solve for the deuteron ground state with Reid soft core potential, and obtain the covergence behaviour as a function of step size.
