Abstract

The damping of isoscalar giant quadrupole resonance in O16 is studied using extended random-phase-approximation approaches derived from the time-dependent density-matrix theory. It is pointed out that the effects of ground-state correlations bring strong fragmentation of quadrupole strength even if the number of two-particle–two-hole configurations is strongly limited.
