Proton orbital effects in the second minimum of doubly odd132Pr

Second minimum structures have been observed for the first time in the doubly odd nucleus ${}_{59}^{132}$Pr. Two new bands are interpreted as based on the $\ensuremath{\pi}{g}_{9/2}[404]9/2\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{13/2}[660]1/2$ configuration and a third as the $\ensuremath{\pi}{h}_{11/2}[532]5/2\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{13/2}[660]1/2$ configuration. Signature splitting effects observed in the $\ensuremath{\pi}{(g}_{9/2}{)}^{\ensuremath{-}1}$ 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 $\ensuremath{\pi}{(g}_{9/2}{)}^{\ensuremath{-}1}$ bands.
