- 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.

Smooth Termination of Rotational Bands in 62Zn: Evidence for a Loss of Collectivity
- 1998
-
In: Physical Review Letters. - 1079-7114. ; 80:12, s. 2558-2561
-
Journal article (peer-reviewed)abstract
- Two sets of strongly coupled rotational bands have been identified in Zn-62. These bands have been observed up to the terminating states of their respective configurations. Lifetime measurements indicate that the transition quadrupole moments in these bands decrease as termination is approached. These results establish the first terminating states of rotational bands in the A similar to 60 mass region and confirm the predicted loss of collectivity associated with smooth band termination.
