  We consider the hadroproduction of chi_{c1} and chi_{c2} mesons and their
subsequent radiative decays to J/psi mesons and photons in the factorization
formalism of nonrelativistic quantum chromodynamics, and study the decay
angular distributions, by means of helicity density matrices, in view of their
sensitivity to color-octet processes. We present numerical results appropriate
for the Fermilab Tevatron.
