Ab initio calculation of electron affinities and level structures have been obtained by adding a simple approximate correlation-potentia1 term to the usual pseudo-relativistic Hartree-Fock Hamiltonian. Results for the following systems the 2s2p2 and 2p3 configurations of Be-, the p 3 configurations of C-, Si-, Ge-, Sn-and Pb-, the ? p and sp2 configurations of Mg-, Ca-, Sr-, Ba-and Ra-, and the ? p and sp2 configurations of Zn-, Cd-and Hgare reported here and compared, when possible, with earlier theoretical and experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
