Abstract：
Using the GCM method and taking the coupling between collective octupolevibration and noncollective particle-hole configurations into account, the quadrupole moment Q(3 ^－), the reduced octupole transition probability B( E3) and the variation of the transition density ρ ^tr ₃with respect to the radial distance are calculated. We found that Q(3 ^－)－0.098eb and B( E3) =38 w.u.. It is shown that the desired results can be obtained by taking the core-excitation into account microscopically in the GCM framework without introducing the usual effective charge of nucleons.
