Consider a particle of mass u and charge e in the central potential. V(r) = 4or' e Απεργ 0 R where the Coulombic force is shielded. The difference can be considered negligible if the parameter →0. Consider this difference as a perturbation and calculate the first order correction of the ground state energy.
