Megjegyzések:	The decay of a new four-quasiparticle isomeric state in 160Sm has been observed using [gamma]-ray spectroscopy at the RIBF, RIKEN. The four-quasiparticle state is assigned a 2??2??5/2?[532], ?5/2+[413], ?5/2?[523], ?7/2+[633] configuration. The half-life of this (11+) state is measured to be 1.8(4) ?s. The (11+) isomer decays into a rotational band structure, based on a (6?) ?5/2?[523]??7/2+[633] bandhead, consistent with the gK?gR values. This decays to a (5-) two-proton quasiparticle state, which in turn decays to the ground state band. Potential energy surface and blocked-BCS calculations were performed in the deformed midshell region around 160Sm. They reveal a significant influence from ?6 deformation and that 160Sm is the best candidate for the lightest four-quasiparticle K isomer to exist in this region. The relationship between reduced hindrance and isomer excitation energy for E1 transitions from multiquasiparticle states is considered with the new data from 160Sm. The E1 data are found to agree with the existing relationship for E2 transitions.

Megjegyzések:	Excited states in the N=102 isotones 166Gd and 164Sm have been observed following isomeric decay for the first time at RIBF, RIKEN. The half-lives of the isomeric states have been measured to be 950(60) and 600(140) ns for 166Gd and 164Sm, respectively. Based on the decay patterns and potential energy surface calculations, including ?6 deformation, a spin and parity of 6? has been assigned to the isomeric states in both nuclei. Collective observables are discussed in light of the systematics of the region, giving insight into nuclear shape evolution. The decrease in the ground-band energies of 166Gd and 164Sm (N=102) compared to 164Gd and 162Sm (N=100), respectively, presents evidence for the predicted deformed shell closure at N=100.

Megjegyzések:	Neutron-rich Pm (Z = 61) isotopes were studied by delayed ?-ray spectroscopy at RIBF; Riken Nishina Center using the in-flight fission of 345 MeV/u 238U beam. An array of cluster-type Ge detectors; EURICA; was used to measure the delayed ? rays from stopped ions. Isomers were observed in 158Pm; 159Pm and 161Pm with half-lives of >16; 4.64(21), and 0.88(10) ?s respectively. Preliminary level schemes for 159Pm and 161Pm were constructed in this study. They have ground-state bands similar to those of 153Pm and 155Pm. The isomeric state of 161Pm could be interpreted as a two quasi-particle excitation of neutrons with configuration of ?7/2[633]??1/2[521] as other K?=4? isomers observed systematically in other N = 100 isotones.
