Abstract
Results of shell-model calculations for lower [Formula Presented]-shell nuclei show that SU(3) symmetry breaking in this region is driven by the single-particle spin-orbit splitting. However, even though states of the yrast band exhibit SU(3) symmetry breaking, the results also show that the yrast band [Formula Presented] values are insensitive to this fragmentation of the SU(3) symmetry; specifically, the quadrupole collectivity as measured by [Formula Presented] transition strengths between low lying members of the yrast band remain high even though SU(3) appears to be broken. Results for [Formula Presented] and [Formula Presented] using the Kuo-Brown-3 two-body interaction are given to illustrate these observations. © 2000 The American Physical Society.
