ORBITAL CONFIGURATION ASSIGNMENT OF 4SE DOUBLY EXCITED-STATES OF LITHIUM ISOELECTRONIC SEQUENCE

Results of Hartree-Fock and multiconfiguration Hartree-Fock calculations using only two configurations (degenerate in zero order within the context of the nuclear-charge-expansion perturbation method) for Se4 doubly excited states of lithium isoelectronic sequence are used to propose an orbital configuration classification of these states, extending the similar classification by Holoien and Geltman for Se4 states of lithium only. © 1979 The American Physical Society.
