Attenuation of Coriolis interaction in rotational model with truncated single-particle basis

Attenuation of Coriolis interaction in frames of combined variant of rotational model based on σ-factor method is calculated. The given model makes use of representations of self-consistent cranking model to describe valent nucleons and phenomenological model based on solution of differential equation to establish core rotation frequency dependence on spin with availability of aligned angular momentum. Concrete calculations are carried out on the example of 164Er, which yrast-band peculiarities are caused by availability of aligned angular momentum. Estimated yrast-band energies confirm applicability of σ-factor method used in solutions of truncated basis problems to description of attenuation of Coriolis interaction
