An outstanding mystery of charmonium physics is why the J/{psi} decays prominently to pseudoscalar plus vector meson channels, such as J/{psi}{r_arrow}{rho}{pi} and J/{psi}{r_arrow}K{sup {asterisk}}K , whereas the {psi}{sup {prime}}(2S) does not. We show that such decays of J/{psi} and their suppression for {psi}{sup {prime}}(2S) follow naturally from the existence of intrinsic charm {vert_bar}{ovr q}q{ovr c}c{r_angle} Fock components of the light vector mesons. {copyright} {ital 1997} {ital The American Physical Society}
