摘要：

Spin-free first-order relativistic calculations have been carried out on Au, Hg at the SCF level and on Au2 and Hg22+ at the CI level using the size-consistent CPF procedure. The atomic SCF results agree with previous relativistic atomic calculations using the Cowan-Griffin procedure to within 0.5 eV. The spectroscopic constants calculated for Au2 agree fairly well with experiment and with previously published relativistic effective core potential results. For Hg22+ we obtain, in contrast to previous theoretical results, a relativistic destabilization of the binding energy. © 1990.
