Calculation of the second electron affinities of atoms

Abstract

The second electron affinities of the atoms helium to krypton are calculated using the self-interaction corrected generalized exchange local-spin-density functional theory with the correlation energy functional. The dependence of the second electron affinities of the elements O, S, and Se on the Watson sphere radius is discussed. The present results are compared with other theoretical values and experimental data for the elements helium through krypton. Keywords: second electron affinity, density functional theory.
