Abstract
Measurements of , , and subshell cross sections have been performed on polycrystalline Ba. These results essentially confirm many-body atomic calculations including the resonant enhancement of photoemission from the outer shells at the threshold. Evidence is also presented for a two-electron discrete excited state about 20 eV above the threshold.
