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.
