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 130Pr using Gammasphere and the Microball charged-particle detector array. These bands involve the important g9/2[404]9/2 proton orbital. This new information on 130Pr 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 i13/2[660]1/2 neutron intruder orbital at the boundary of the A=135 superdeformed region.
