Abstract

The near-drip-line nucleus 127Pr was populated with the reaction 92Mo(40Ca,𝛼⁢𝑝) at a beam energy of 175 MeV. Particle-𝛾-𝛾 coincidences were collected, and the total energy plane gating technique was used to enhance events associated with the 𝛼⁢𝑝 exit channel. This enabled two new rotational bands to be assigned to 127Pr, 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 [404]⁢9/2+proton orbital. The occupancy of this orbital is associated with enhanced quadrupole deformation in this mass region.
