Abstract

γ-ray transitions have been identified for the first time in the near-drip-line nucleus ¹²⁶Pr, making it the lightest odd-odd praseodymium nucleus in which excited states have been reported. Evidence is presented for two rotational bands in ¹²⁶Pr, one strongly coupled and the other doubly decoupled. In addition, the preliminary reports of a band in ¹²⁸Pr are confirmed. The signature inversion phenomenon and trends in the energy staggering of the π_11/2νh_11/2 bands are discussed for the Cs, La, and Pr nuclei.
