A relativistic Foclc-space coupled cluster theory based on the Dirac-Coulomb-Breit wavefunctions has been developed and implemented, employing analytic basis sets of Gaussian-type functions. Relativistic all-order calculations including single and double excitations were performed for the ground sta
The lowest order relativistic corrections to the electronic energies have been computed for the B 1E u state of H 2 in the interval 1.0 ~< R ~< 30 a 0. The total correction at the equilibrium separation, R = 2.43 a o amounts to -2.126 cm-1. The absolute shifts of the vibrational levels of H 2 change
The method of the evaluation of the upper and lower bounds of the second-order perturbation of the energy is described. The calculation of upper and lower bounds for the second-order perturbation of the energy in l/Z expansions for two-electron atoms are given.
