Proton orbital effects in the second minimum of doubly odd 132Pr

Second minimum structures have been observed for the first time in the doubly odd nucleus Pr-132(59). Two new bands are interpreted as based on the pi g(9/2)[404]9/2x nu i(13/2)[660]1/2 configuration and a third as the pi h(11/2)[532]5/2x nu i(13/2)[660]1/2 configuration. Signature splitting effects observed in the pi(g(9/2))(-1) bands provide new information regarding the positive parity proton orbitals at large deformation. Results from the extracted B(M1)/B(E2) ratios are consistent with a large deformation for the pi(g(9/2))(-1) bands.
