The IBM description of triaxial nuclei

Popis výsledku v původním jazyce

Recently, interacting boson model (IBM) calculations, in the O(6) basis up to the seniority quantum number v(max) = 40, were made possible thanks to the availability of the SO(5) Clebsch-Gordan (CG) coefficients, computed in floating-point arithmetic (T.A. Welsh, unpublished ( 2008)). In this paper we have made use of these CG coefficients to extend the IBM to situations where triaxial deformation is present. Such a description has been considered in the algebraic collective model (ACM) which is an algebraic version of the Bohr model. To describe triaxiality in the ACM a term proportional to cos(2) 3 gamma. must be included in the Hamiltonian. We show that, in the IBM, this can be achieved by including a term quadratic in ((Q) over cap circle times (Q)over cap circle times ($) over cap)(0), which is an IBM image of the term cos(2) 3 gamma.
