N2 - The ground state energy of a hydrogenic atom of nuclear charge Z, perturbed by a polynomial perturbation 2 lambda Zr+2 lambda 2r2, is calculated by means of a variational modification of Rayleigh-Schrodinger perturbation theory, which is effective for all negative lambda.
AB - The ground state energy of a hydrogenic atom of nuclear charge Z, perturbed by a polynomial perturbation 2 lambda Zr+2 lambda 2r2, is calculated by means of a variational modification of Rayleigh-Schrodinger perturbation theory, which is effective for all negative lambda.
