The K = 0 bands in doubly odd nuclei [1, 2] are known to display an additional energy shift due to residual n- p interaction [3], which is known as the Newby shift [4,5]. This shift is not fully understood even now, particularly the sign of the shift. We have analyzed the updated and new experimental data of all the K= 0 bands in odd – odd nuclei [6, 7] available in the rare earth region. The calculations have been done within the framework of Two Quasiparticle plus Rotor Model (TQPRM) [1], so that the effect of Coriolis mixing could be accommodated in the Newby shift calculations. Of particular interest are the Ωp = Ωn = ½, K = 0 bands where an additional decoupling term also comes into play. A total of 36 K = 0 bands have been analyzed. The reverse sign of the Newby shift in many cases is explained by the calculations. References:
