Times Cited Count:6 Percentile:45.53(Physics, Nuclear)Excited states in neutron-rich W have been populated via deep inelastic collisions of a 630-MeV Se beam on a W target. Projectile-like fragments were measured by an annular Si detector for reaction channel selection. Delayed rays from target residues were detected by means of the so-called recoil shadow technique. A new isomer at 411 keV, based on the [615] Nilsson configuration, has been identified with the half-life of 1.56(28) s. The decay rates of the isomers are discussed in terms of the quantum number by comparison with the systematics from the neighboring nuclei.

Times Cited Count:13 Percentile:71.74(Physics, Nuclear)Excited states in Ba, populated in deep-inelastic collisions by the interaction of 450-MeV Se ions with a La target, have been studied by means of in-beam -ray spectroscopy. A new isomer with has been identified at an excitation energy of MeV. The half-life was determined as ns. The extracted value is much smaller than those in Te and Xe. This hindrance is investigated by a shell model calculation.
