摘要
The most neutron-deficient isotopes215,216 U were produced in the complete-fusion reaction ^(180)W(^(40)Ar, 4-5n)^(215,216) U. Evaporation residues recoiled from the target were separated in-flight from the primary beam by the gas-filled recoil separator SHANS and subsequently identified on the basis of correlated α-decay chains. Two α-decaying states were identified in ^(216)U, one for the ground state and the other for the isomeric state with 8+(πh_(9/2)πf_(7/2)) configuration. The α-decay properties for ^(215,216)U and the systematics of 8+isomeric state in N = 124, 126 isotones were investigated.
The most neutron-deficient isotopes 215,216U were produced in the complete-fusion reaction 180W（40Ar, 4-5n）215,216U. Evaporation residues recoiled from the target were separated in-flight from the primary beam by the gas-filled recoil separator SHANS and subsequently identified on the basis of correlated a-decay chains. Two a-decaying states were identified in 216U, one for the ground state and the other for the isomeric state with 8＋（πh9/2πfT/2） configuration. The a-decay properties for 215,216U and the systematics of 8＋ isomeric state in N = 124,126 isotones were investigated.
