β-decay spectroscopy of neutron-rich $^{160,161,162}$Sm isotopes

Abstract : Neutron-rich ^160,161,162Sm isotopes have been populated at the RIBF, RIKEN via beta first time. beta-coincident gamma rays were observed in all three isotopes including gamma rays from the isomeric decay of ^160Sm and ^162Sm. The isomers in ^160Sm and ^162Sm have previously been observed but have been populated via beta decay for the first time. The isomeric state in ^162Sm is assigned a [??] configuration based on the decay pattern. The level schemes of ^160Sm and ^162Sm are presented. The ground states in the parent nuclei ^160Pm and ^162Pm are both assigned a [??] configuration based on the population of states in the daughter nuclei. Blocked BCS calculations were performed to further investigate the spin-parities of the ground states in ^160Pm, ^161Pm, and ^162Pm, and the isomeric state in ^162Sm
