Intrinsic State for an extended version of the interacting boson model ( IBM - 4 )
نویسنده
چکیده
An intrinsic-state formalism for IBM-4 is presented. A basis of deformed bosons is introduced which allows the construction of a general trial wave function which has Wigner’s spin–isospin SU(4) symmetry as a particular limit. Intrinsic-state calculations are compared with exact ones showing good agreement. PACS numbers: 21.60 -n, 21.60 Fw, 21.60 Ev

متن کاملA pr 1 99 8 Intrinsic structure of two - phonon states in the interacting boson model
A general study of excitations up to two-phonon states is carried out using the intrinsic-state formalism of the Interacting Boson Model (IBM). Spectra and transitions for the different dynamical symmetries are analyzed and the correspondence with states in the laboratory frame is established. The influence of multi-phonon states is discussed. The approach is useful in problems where the comple...

A Hartree–Bose mean-field approximation for the IBM-3 is presented. A Hartree–Bose transformation from spherical to deformed bosons with chargedependent parameters is proposed which allows bosonic pair correlations and includes higher angular momentum bosons. The formalism contains previously proposed IBM-2 and IBM-3 intrinsic states as particular limits. Typeset using REVTEX 1 With the advent ...

The dynamical symmetries in even-even nuclei were investigated by Arima and Iachello in 1974, and led to a model called ;ampquotInteracting Boson Model, (IBM)". In this article we have outlined some basic ideas used in IBM-1 and carried out the calculations for low laying energy levels of even-even isotopes Cd, Sn and Te via PHINT code. The calculations for energy and quadra pole moment t...
