The variable moment of inertia model has been applied to the K+=(&OHgr;p+&OHgr;n) bands which are relatively free from Coriolis mixing. The inertia parameter shows significant variation with angular momentum which is nearly identical to one of the odd‐A rotational bands based on either the neutron or the proton configuration also involved in the odd‐odd band. An explanation in terms of the blocking effect of pairing correlations is presented.
