ΔK=0 admixed band structures in the odd-odd deformed ¹⁷⁶₇₁Lu₁₀₅

Studies relating to the naturally occurring odd-odd heavy nucleus ¹⁷⁶Lu are of a great interest both from the astrophysical/nucleosynthesis and the nuclear structure points of view. Its level scheme has been experimentally investigated, using 9 different processes including Coulomb excitation, n-capture and particle transfer reactions etc. Over 30 two-quasiparticle (2qp) Nilsson configurations and associated rotational bands have been identified therein. One of its features, rarely observed elsewhere but in marked evidence herein, is ΔK=0 2qp configuration mixing of several bands. In the present report, we specifically focus on this phenomenon. In particular, we seek a quantitative measure of ΔK=0 mixing in 16 bands comprising of 4 pairs of GM doublets wherein identical K_T and K_S bands pertain to differing (n,p) configurations
