摘要：

We use the new symmetries in the heavy quark limit to calculate the exclusive B decays B-->Kpsi(psi') and B-->K*psi(psi'). The estimated decay rates are compared with experimental values. We also estimate the rare B-->K*gamma decay rate, based on these experimental data and heavy quark symmetry.
