Description

Gamma rays decaying from the excited states of the proton-unbound 151Lu were observed for the first time in an experiment using the 96Ru(58Ni,p2n)151Lu reaction. These γ rays were identified by correlating prompt γ radiations at the target position with 151Lu proton radioactivities at the focal plane of a recoil mass separator. Systematic data on N=80 isotones suggest a possible isomeric level at high spin in 151Lu. Our measurement was unable to observe such an isomer, but provided an upper limit on its half-life. The observed γ rays in 151Lu can be interpreted in terms of two possible level structures. copyright 1998 The American Physical Society
