A microscopic analysis of moments of inertia

Jing-Ye, Zhang and Åberg, Sven LU (1982) In Nuclear Physics, Section A 390(2). p.314-335
Abstract

A microscopic analysis of moments of inertia is performed within the cranked Nilsson model. Special emphasis is put on the second-derivative moment of inertia, J(2). Contributions to this from changes of rotational frequency and deformation are separately discussed. A simple expression for the latter is derived and it is for a studied series of Yb isotopes usually found to contribute with less than 10% to the total J(2) value. J(1), J(2) and Jrigid are calculated as functions of spin at the appropriate equilibrium deformations for the even-even nuclei 160-176Yb. Variations of J(2) with particle number and spin are discussed. Relations between J(2)... (More)

Variations of J(2) with particle number and spin are discussed. Relations between J(2) and the deformation are studied in detail, especially in connection with the super-backbending.
