Hyperbolic Dependence of Moment of Inertia onω2 in Bands Involving vi13/2 Orbital and its Application in Configuration Identification

The so-called hyperbolic dependence of apparent moment of inertia on square of rotational frequency is developed to the bands involving^13/2 quasineutron around A-60 lighter rare-earth region.This can be explained as a characteristic of strongly Coriolis mixing in the high-j unique-parity bands.As applications of such an effectj the previously proposed assignments of band x of^(160)Ho,π1/2^(-)[541]■vi_(13/2)band of^(170)Ta,as well as band B of 168Lu have been reviewed respectively.
