Abstract: (APS)
The interplay between the quadrupole-quadrupole and spin-orbit interactions in nuclei is analyzed in an SU(3) basis. Results for two ds-shell nuclei 20Ne and 22Ne and one fp-shell nucleus 44Ti are considered for realistic values of the strength parameters of these two interactions. The ground state band is built from the S=0 leading irreducible representation (irrep), which mixes strongly with the leading S=1 irreps in the proton and neutron subspaces. The quadrupole-quadrupole interaction is found to give dominant weights to the “stretched” coupled representations, which supports a strong truncation of the Hilbert space.
