Title: ANALYSIS OF $Ba^{++}$ PHOTOABSORPTION SPECTRA: COMPARISON WITH XeI, BaI AND BaXI

Abstract: Photoabsorption in a controlled doubly ionized plasma (fully ionized and in the ground state) of $Ba^{++}$ revealed several long series arising from the 4d and 5p closed shells. The following series have been observed: (1) $4d^{9}$ np (to n=14), (2) $5p^{5}$ ns (to n=20), and (3) $5p^{5}$ nd (to n=19). These spectra can be directly compared with existing published and unpublished isoelectronic spectra of XeI. Series (2) and (3) are strongly mixed and are treated by multi-channel quantum defect theory. Transitions to $4d^{9}$ nf $^{3}D_{1}, ^{3}P_{1}$, and $^{1}P_{1}$, not seen in XeI, were identified. They are bracketed by the previously identified, corresponding transitions in BaI and Ba XI.
