Unusual Features of rotational bands in 184Au deformed doublyodd nucleus

Abstract

Two-quasiparticle rotational bands of doubly-odd 184 Au have been investigated. The two quasiparticle plus rotor model (TQPRM) calculations are done for the bands where sufficient experimental data is available mainly for the ground state band{3/2(532)π  7/2(514)v}and the excited bands with configuration {1/2(660)π  9/2(624)v} and {1/2(541)π  9/2(624)v}. Peculiar features like second point of signature inversion, signature reversal and band crossing are observed in these bands of 184 Au. The ambiguity regarding the configuration assignment of ground state band is resolved. The calculations for ground state band clearly show that the proton orbital changes from 3/2(532)π to 1/2(541)π with increasing spin. The mechanism of unusual feature like second point of signature inversion is also presented.
