Classifications in the Spectra of Autoionization Electrons from Lithiumlike Oxygen and Fluorine

Abstract

We suggest some classifications for the spectra observed by Sellin et al. [Phys. Rev. Letters 27, 1108 (1971)] of autoionization electrons from highly ionized oxygen and fluorine atoms, and comment on some of their suggestions. They appear to have observed the lowest nonautoionizing doubly excited doublet term in the Li r sequence, $1s2{p}^{2}^{2}P$. High-angular-momentum states may be responsible for their observed resonances of higher energy.
