Abstract
High spin states in and have been studied with the “unsafe” Coulomb excitation technique. In each nucleus, signature partner rotational bands built on the and orbitals of respective and parentage have been delineated. An additional pair of bands based on the state was also observed in . New information on the even-even and transfer products is also presented. From the present data, the role of protons in generating angular momentum in the even-even nuclei of the region is documented. A satisfactory description of the evolution of the rotational sequences with spin is achieved within the framework of the cranked shell model. Nevertheless, when combined with information on odd-neutron nuclei available from elsewhere, the data highlight significant shortcomings of the available theoretical predictions.
