Abstract: | The nucleus 73 Se was studied by the reaction 51 V(28 Si,αpn)73 Se. The level scheme extended upto $frac{{41}} {2}bar h $ in both +ve and ?ve parity bands with 10 new transitions placed in the level scheme. Lifetimes of 17 high spin states measured by DSAM. The transitional quadrupole moment is found to drop down after the band crossing suggesting a less deformed configuration. At the band crossing region, Q t increases suddenly in both +ve and ?ve parity bands. It is argued that the +ve parity band is a decoupled band. |
