SU(3) realization of the rigid asymmetric rotor within the IBM
Yuri F. Smirnov, Nadya A. Smirnova, Piet Van Isacker
It is shown that the spectrum of the asymmetric rotor can be realized quantum mechanically in terms of a system of interacting bosons. This is achieved in the SU(3) limit of the in…
Excitation of multiple giant dipole resonances: from spherical to deformed nuclei
M. V. Andres, E. G. Lanza, P. Van Isacker +2
The effect of deformation on the excitation of multiple giant dipole resonances is studied. Analytical expressions are derived in the framework of the interacting boson model for t…
An intrinsic state for an extended version of the interacting boson model
J. E. Garcia-Ramos, J. M. Arias, J. Dukelsky +1
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…
