SU(3) Realization of the Pairing-plus-Quadrupole Model
in One or More Oscillator Shells


című előadása hangzik el.

Kivonat:
An extended pairing-plus-quadrupole model, realized in the framework of
the Elliott SU(3) scheme, is used to study the combined effects of the
quadrupole-quadrupole, pairing, and single-particle interactions on energy
spectra and ground state shapes of ds-shell nuclear systems. The pairing
part of the Hamiltonian consists of pp-, nn- and pn-pairing terms. In case
when more than one oscillator shells are involved, terms describing the
pair-scattering between two shells are also included in the interaction.
Results for nuclear systems are calculated for a reasonable choice of
values for the interaction parameter strengths. We propose the build up of
a refined version of the model based on existing good (pseudo-) SU(3)
symmetry.
