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 {sup 130}Pr using Gammasphere and the Microball charged-particle detector array. These bands involve the important g{sub 9/2}[404]9/2 proton orbital. This new information on {sup 130}Pr 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{sub 13/2}[660]1/2 neutron intruder orbital at the boundary of the A=135 superdeformed region. {copyright} {ital 1997} {ital The American Physical Society}
