  A study of prompt photon plus associated jet production is performed at
next-to-leading order (O($\alpha\alpha_s^2$)) in QCD at $\sqrt{S}=200-500$ GeV,
appropriate for the RHIC polarized $\vec{p}\vec{p}$ collider experiment.
Momentum correlations between the jet and photon are examined and the utility
of the process as a method for constraining the size and shape of the polarized
gluon density of the proton $\Delta G$ is examined.
