  A second order, $O(\alpha ^2_s)$, calculation in perturbative quantum
chromodynamics of the two particle inclusive cross section is presented for the
reaction $p +\bar{p}\rightarrow \gamma + c + X$ for large values of the
transverse momentum of the prompt photon and charm quark. The combination of
analytic and Monte Carlo integration methods used here to perform phase-space
integrations facilitates imposition of photon isolation restrictions and other
selections of relevance in experiments. Differential distributions are provided
for various observables. Positive correlations in rapidity are predicted.
