摘要：

An outstanding mystery of charmonium physics is why the J/psi decays prominently to pseudoscalar plus vector meson channels, such as J/psi --> rho pi and J/psi --> K*K, whereas the psi'(2S) does not. We show that such decays of J/psi and their suppression for psi'(2S) follow naturally from the existence of intrinsic charm \(q) over bar q (c) over bar c] Fock components of the light vector mesons.
