We apply many-body theory techniques, particularly the Dyson equation, to interactions of an electron with an atom having filled subshells. This method is a unified treatment of different but related problems; electron scattering, negative ions, and photoionization of negative ions. We present calculated results for these problems: the systems electron + He(3S), Pd, Ca, Sr, and Ba, scattering phases, electron binding energy, wave functions, and photoemission.
