Matrix elements of scalar three-electron operators for the atomic f shell

Abstract

Tables are provided for the matrix elements of an orthogonal set of Hermitian three-electron operators ti for the states of the f shell. The ti are scalar with respect to the total spin S and total orbital angular momentum L, and they are among the effective operators needed to be included in an f-electron Hamiltonian in order to represent the coupling of the ground configuration fN to excited configurations via the interelectronic Coulomb interaction. © 1996 Academic Press, Inc.
