Generalized quasispin formalism and fermion bases of the model of interactable bosons

Abstract

A relatively simple, detailed microscopic calculation of IBM parameters based on the generalized quasi-spin formalism is proposed, by including in the theory of the double tensor, acting in the spaces, both angular moments and generalized quasispins. The method is applied to the study of the structure of the collective state of even isotopes Xe 130 118 . The spectrum and probabilities of electromagnetic transitions of nuclei are calculated and they are compared with the available experimental data.
