Study of alignments in normal deformed bands of ¹⁶⁵Lu

The Lu isotopes with Z=71 show a variety of nuclear shapes. Andgren et al. have performed a fusion evaporation experiment to investigate the triaxiality and determined the lifetimes of medium spin states in ¹⁶⁵Lu. They have performed the total routhian surface (TRS) and particle rotor model calculations. The TRS calculations have predicted the axial shapes for 9/2^-(514), 7/2⁺(404) and 1/2^-(541) bands. The ¹⁶⁵Lu has normal deformed bands and triaxial super deformed bands. The low-spin states of normal deformed bands of ¹⁶⁵Lu were known previously and they were extended to higher spin by Schnwaber et al. Except one negative parity band all the normal deformed bands are coupled bands and their both signatures are known. Motivated by the availability of experimental data on multiple normal deformed bands in this isotope, the low-spin states of these bands are investigated by using projected shell model (PSM) framework
