Abstract

The odd-proton nuclei Pr-127 and Pm-131 have been investigated using the Ru-96(Cl-35,2p2n) and Ru-96(Ca-40, alpha p)/Ru-96(K-39,2p2n) reactions, respectively, at beam energies of 164, 180, and 186 MeV. States belonging to the yrast bands of Pr-127 and Pm-131, which are interpreted as being based upon the h(11/2)[541]3-/2 proton configuration, have been observed from the 11-/2 band head to spin 47-/2. The properties of these two new structures are observed to be different to those of similar configurations in the heavier odd mass isotopes. The systematics of the band crossings in the pi h(11/2) bands of the odd mass Pr and Pm isotopes are discussed and compared with extended total Routhian surface calculations. [S0556-2813(98)03505-5].
