Abstract
High-spin states have been populated in the neutron-deficient [Formula Presented] nuclei via the [Formula Presented] reaction at a beam energy of 180 MeV. Transitions within the Sm nuclei were enhanced by using the Microball charged particle array and [Formula Presented]-ray de-excitation was studied using Gammasphere. A new highly deformed band has been observed in the data and assigned to [Formula Presented] Comparison of the properties of the new band with Woods-Saxon cranking calculations suggests that it is built upon a [Formula Presented] configuration. The band shows evidence for an interaction at [Formula Presented] This has tentatively been interpreted as resulting from a crossing between the [Formula Presented] signatures of the [Formula Presented] and [Formula Presented] proton orbitals. The previously known [Formula Presented] intruder band in [Formula Presented] was also observed and extended to higher rotational frequency. Both structures show good agreement with extended total Routhian surface calculations.
