{gamma}-ray transitions have been identified for the first time in the near-drip-line nucleus {sup 126}Pr, making it the lightest odd-odd praseodymium nucleus in which excited states have been reported. Evidence is presented for two rotational bands in {sup 126}Pr, one strongly coupled and the other doubly decoupled. In addition, the preliminary reports of a band in {sup 128}Pr are confirmed. The signature inversion phenomenon and trends in the energy staggering of the {pi}h{sub 11/2}{nu}h{sub 11/2} bands are discussed for the Cs, La, and Pr nuclei.
