Abstract
The SO(7) limit of the fermion dynamical symmetry model (FDSM) is disc ussed. Using the vector coherent state theory (VCST), we construct the matrix elements of quadruple pair (D-dagger) and quadrupole (P-2) ope rators explicitly, then obtain a selection rule for E2 transition and a formula for the E2 transition rates of the SO(7) limit. As an experi mental evidence of the FDSM's SO(7) limit, the B(E2) values for the Pd -Ru region in this way are calculated, and the predicted results are i n good agreement with the experimental data.
