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