Abstract
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 i.
