Abstract

A thorough survey of the literature has shown that fluorescence yields of barium are not well covered even though they are an element of major importance in electron beam ion trap (EBIT) devices. This work is meant to contribute towards filling in this gap by presenting new relativistic calculations for the K-, L-and M-shell fluorescence yields of barium, using the Dirac-Fock (DF) approach. Our results show good agreement with previous results for the K- and L-shells. There are no theoretical or experimental references for the M-shell, making these calculations the first ones performed for this shell.
