Abstract

The near-drip-line nucleus [Formula Presented] Pr was populated with the reaction [Formula Presented] Mo[Formula Presented] Ca,[Formula Presented] at a beam energy of 175 [Formula Presented] V. Particle-[Formula Presented]-[Formula Presented] coincidences were collected, and the total energy plane gating technique was used to enhance events associated with the [Formula Presented] exit channel. This enabled two new rotational bands to be assigned to [Formula Presented] Pr, including a strongly coupled structure. Its similarity with analogous bands in heavier Pr isotopes suggests this structure is most likely based on a hole in the extruder [Formula Presented]proton orbital. The occupancy of this orbital is associated with enhanced quadrupole deformation in this mass region.
