Abstract

A modified version of the shifted 1/N expansion method is formulated for constrained quantum mechanical system. This method is applied to boxed-in hydrogen atom and spherical harmonic oscillator. Results from the shifted 1/N expansion method are compared with the exact numerical results in case of hydrogen atom, and with approximate analytical results in case of the spherical harmonic oscillator. Agreement between the results is found to be good in both the cases.
