Abstract

Previous time-dependent Hartree-Fock (TDHF) calculations of collisions between He ions and He atoms have been extended with improved accuracy. New features include using a Hermitian Coriolis term and installing classical quantum coupling, which allows completely self-consistent treatment of both the nuclear and electronic coordinates. Increased computer capabilities have allowed us to eliminate previous numerical limitations. We have calculated the single- and double-capture cross sections in the energy range of 1 to 250 keV. Comparison with experiments allows us to investigate the strengths and weaknesses of TDHF theory. Since correlation is best defined to be that which is not included in single-particle descriptions, we discuss converged results with regard to what they reveal about correlation.
