Abstract

Neutron-rich ^160,161,162Sm isotopes have been populated at the RIBF, RIKEN via β decay for the first time. β-coincident γ rays were observed in all three isotopes including γ rays from the isomeric decay of ¹⁶⁰Sm and ¹⁶²Sm. The isomers in ¹⁶⁰Sm and ¹⁶²Sm have previously been observed but have been populated via β decay for the first time. The isomeric state in ¹⁶²Sm is assigned a 4^- ν7/2 ⁺[633]⊗ν1/2^-[521] 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 6^- ν7/2⁺[633] ⊗ π5/2 ^- [532] 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.
