Doubly-Excited States of the Be Atom in the MCRRPA

POSTER

Abstract

Photoionization parameters for double-excitation autoionization resonances in neutral beryllium are calculated in the multiconfiguration relativistic random-phase approximation (MCRRPA). Precise energies and widths of all five Rydberg series of low-lying doubly-excited states are given.
