摘要
The high-spin states of 160Lu are populated by the fusion-evaporation reaction 144Sm(19F,3n)160 Lu at beam energies of 90 and 106 Me V.A new level scheme of 160Lu is established.A possible isomeric state based on the πh11/2 (0) υh9/2 configuration is observed.The new decoupled band with the configuration of πd3/2[411]1/2^(+) (0)υi13/2[660] 1/2^(+) is established,and the configurations of these similar decoupled bands in the neighboring odd-odd 162-166 Lu nuclei are suggested.A positive parity coupled band is assigned as the πd5/2[402]5/2^(+)(0)υi13/2[660]1 /2^(+)configuration.
