The many-body theory of Brueckner and Goldstone is used to calculate the correlation energy difference between CH and the carbon atom. Our result is — 0.047 a.u., obtaineu from a single center expansion and a complete set of states appropriate to t

We use approximate Sommerfeld-Maue plus Volkov states to investigate the relativistic and final-state Coulomb-potential effects in strong-field multiphoton-ionization processes. Nonperturbative calculations are carried out for Dirac hydrogenlike atom

The effects of relaxation on the photodetachment of the iodine negative ion are calculated using the recently developed relativistic random-phase approximation with relaxation. In this method the outgoing electron is calculated in the field of the re

A procedure is presented for calculations of double-perturbation problems in the coupled-cluster formalism. With use of this method to include to all orders the correlation effects of single and pair excitations, the enhancement factor R=-585 is obta

The photoionization cross section and angular distribution asymmetry parameter of the 4d10 subshell of atomic barium have been calculated using many-body perturbation theory and the relativistic random-phase approximation modified to include relaxati

The total cross section and the single-differential cross section in energy for the ionization of the ground-state helium atom by electron impact have been calculated in distorted-wave approximations. The optical potential, or self-energy of the sing
