Query: Bound states of a more general exponential screened Coulomb potential   An alternative approximation scheme has been used in solving the Schrodinger
equation to the more general case of exponential screened Coulomb potential,
V(r)=-(a/r)\[1+(1+br)e^{-2br}]. The bound state energies of the 1s, $2s, and
3s-states, together with the ground state wave function are obtained
analytically upto the second perturbation term.
