  The joint angular distribution of the decay B \to J/\Psi V, where V is an
axial vector or vector resonance, followed by the subsequent decay processes of
the J/\Psi and V is calculated using the covariant density method. In
particular, the case where V is the axial vector meson K_1(1270) which decays
into K \rho is considered as well as the case that V is the vector meson
K^\ast(890) which decays into K \pi.
