Abstract

Two strongly coupled bands with large dynamic moment of inertia values have been observed for the first time in the neutron-deficient odd-odd nucleus Pr-130 using Gammasphere and the Microball charged-particle detector array. These bands involve the important g(9/2)[404]9/2 proton orbital. This new information on Pr-130 coupled with Projected Shell Model calculations provide valuable insight on rotational alignment processes taking place in this mass region, the size of the N=72 deformed shell gap, and the position of the i(13/2)[660]1/2 neutron intruder orbital at the boundary of the A=135 superdeformed region.
