Abstract
We have investigated the cross section for inner (5p) shell ionization of barium by high energy (6 keV) electron impact. The target atoms were in the ground state and in the laser excited metastable 6s 5d (1,3 D) state, respectively. Comparison of the relative ionization cross sections yields information on the configuration mixed wave functions of neutral and ionic barium.

The present work is dedicated to the memory of Prof. Dr. Wolfgang Hink, whose initiative and support for this collaborative experiment through the years 1986 to 1991 was one of the most important contributions to its success. Wolfgang Hink died in December 1991, few days before his 68th birthday, and few months before his retirement from the University of Würzburg
