Abstract
The ground-state rotational band of the neutron-deficient californium () isotope was identified for the first time and measured up to a tentative spin and parity of . The observation of the rotational band indicates that the nucleus is deformed. The kinematic and dynamic moments of inertia were deduced from the measured -ray transition energies. The behavior of the dynamic moment of inertia revealed an up-bend due to a possible alignment of coupled nucleons in high- orbitals starting at a rotational frequency of about . The results were compared with the systematic behavior of the even-even isotones as well as with available theoretical calculations that have been performed for nuclei in the region.
