The implementation of two simple ideas concerning the optimization of a many-electron ground state wavefunction is reported. Firstly, the wavefunction is written as a sum of non-orthogonal Slater determinants. Secondly, the optimization is carried out by adding one determinant at a time and determin
Large-order perturbation theory in the form of the perturbational-variational Rayleigh-Ritz (PV RR) formalism has been applied to excited energy levels in the Stark effect for H?+, yielding non-Born-Oppenheimer electric polarizabilities through 16th, 8th, 4th, and 2nd order, respectively, for the fi
