Abstract
Two new rotational bands have been observed in the Dy-152 nucleus following experiments performed using the EUROGAM gamma-ray spectrometer. Several tr ansitions have been observed that link these new bands into the known singl e-particle states. Using the Doppler shift attenuation method, the quadrupo le moment of the previously-known rotational sequence has been measured. Th e value of Q(band) = 3.85+/-0.06 e b confirms the deformed nature of this c ascade. The structures of the three bands are discussed in terms of the occ upation of both paired and unpaired orbitals, and are found to be in good a greement with theoretical calculations. The observation of two new bands fu rther extends the concept of shape coexistence in the Dy-152 nucleus.
