In-beam spectroscopy of medium- and high-spin states in $^{133}$Ce
Abstract
Medium and high-spin states in Ce were investigated using the Cd(Ne, ) reaction and the Gammasphere array. The level scheme was extended up to an excitation energy of MeV and spin 93/2 . Eleven bands of quadrupole transitions and two new dipole bands are identified. The connections to low-lying states of the previously known, high-spin triaxial bands were firmly established, thus fixing the excitation energy and, in many cases, the spin parity of the levels. Based on comparisons with cranked Nilsson-Strutinsky calculations and tilted axis cranking covariant density functional theory, it is shown that all observed bands are characterized by pronounced triaxiality. Competing multiquasiparticle configurations are found to contribute to a rich variety of collective phenomena in this nucleus.
