Description and Analysis of the Second Spectrum of Tantalum, Ta II

The spectrum has been observed from 2000.73 to 7813.40 A. There are 2,629 lines listed, of which 1,890 have been classified. Observed Zeeman patterns are recorded, as well as g-values. These have aided greatly in the work on analysis. The 61 known even levels have been grouped into 26 terms from the...

description The spectrum has been observed from 2000.73 to 7813.40 A. There are 2,629 lines listed, of which 1,890 have been classified. Observed Zeeman patterns are recorded, as well as g-values. These have aided greatly in the work on analysis. The 61 known even levels have been grouped into 26 terms from the 5d (3) 6s, 5d (2) 6s (2) and 5d (4) configurations. The odd levels number 164; they have no assigned term designations. No series have been found, but the ionization potential is estimated to be between 16.0 and 16.5 electron volts.
