Energy analysis of the electrons ejected in the autoionization of theBa(6pj20s12)Jstates

Analysis of the electrons ejected during the autoionization of the $\mathrm{Ba}{\left(6\mathrm{}{p}_{j}20s_{\frac{1}{2}}\right)}_J$ states shows that for all but the ${\left(6\mathrm{}{p}_{\frac{3}{2}}20s_{\frac{1}{2}}\right)}_1$ state the electrons have ∼2.5 eV of kinetic energy, implying autoionization to the ground ${\mathrm{Ba}}^{+}6s_{\frac{1}{2}}$ state. However, in the autoionization of the anomalously wide ${\left(6\mathrm{}{p}_{\frac{3}{2}}20s_{\frac{1}{2}}\right)}_1$ state, roughly two-thirds of the electrons have an energy of 0.2 eV and one-third have an energy of 2.5 eV, implying that the anomalous width of the $6p_{\frac{3}{2}}20s_{\frac{1}{2}}$ state is due to autoionization to the excited ${\mathrm{Ba}}^{+}6p_{\frac{1}{2}}$ state.
