STRUCTURE AND IONIZATION POTENTIAL OF Hf III AND Hf IV
Structure and ionization potential of hafnium (III) and (IV) were analyzed. As a resuit, almost 8O% of all known Hf III lines were classified as combinations between a low group of 13 even levels belonging to the configurations 5d/sup 2/ 5d6s and 6s/sup 2/, a group of 16 odd levels produced by 5d6p and 6s6p, and 11 high even levels of the 5d7s and 5d6d configurations. The ionization potential derived from the ns/sup 2/S series is 33.30v, with a possible error of about 0.05v. The levels of Hf IV that could be established were 5p/sup 6/5d, 5p/sup 6/6s, 5p/sup 6/6p, 5p/sup 6/7s, and 5p/sup 6/6d. From the two known members of the ns/sup 3/D series converging to the limit Hf IV 5d/ sup 2/D the ionization potential is 23.2v, accurate to within a few 0.1v. (N.W.R.)
