Long-lived isomeric states and quasiparticle band structures in neutron-rich 162,164Gd nuclei from β decay
Abstract
Neutron-rich nuclei 162,164Eu were produced by bombarding a proton beam on a 238U target at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory and mass separating the 162,164Eu products. New level schemes and new γ-ray transitions of the daughters 162,164Gd were identified from β-decay spectroscopy studies. Additionally, half-lives of the 162,164Eu were remeasured to clarify the previous ambiguous results. Two quasiparticle band structures were built and compared with neighboring nuclei. The β and γ bands were extended in 162Gd and a γ band was extended in 164Gd. Half-lives of the isomeric states at (6-) 1449 keV in 162Gd and (4-) 1096 keV in 164Gd were measured to be 99(3) μs and 0.56(3) μs, respectively. Projected shell model calculations were performed and found to be in good agreement with all of the experimental data.
