Description

A Gammasphere experiment has been carried out using the 122Sn(36S,4n) reaction to search for excited superdeformed (SD) structures in 154Dy to investigate the properties of neutron orbitals at superdeformation. Five new excited SD bands have been identified with intensities ranging from ∼0.7% to ∼0.03% relative to the 154Dy reaction channel. Bands SD1, SD3, SD5, and SD6 are interpreted within the cranked relativistic mean field theory by using the effective alignment method. High-N intruder configurations are also discussed for bands SD2 and SD4, based on a comparison of their dynamic moments of inertia, which rise with increasing rotational frequency, with those of similar bands in neighboring nuclei.
