Dj. Hartley et al., First evidence of excited states in the near-drip-line nucleus Pr-126 and signature inversion in A approximate to 130 nuclei - art. no. 041301, PHYS REV C, 6304(4), 2001, pp. 1301
gamma -ray transitions have been identified for the first time in the near-
drip-line nucleus Pr-126, making it the lightest odd-odd praseodymium nucle
us in which excited states have been reported. Evidence is presented for tw
o rotational bands in Pr-126, one strongly coupled and the other doubly dec
oupled. In addition, the preliminary reports of a band in Pr-128 are confir
med. The signature inversion phenomenon and trends in the energy staggering
of the pih(11/2)nuh(11/2) bands are discussed for the Cs, La, and Pr nucle
