We present a next-to-leading order QCD calculation of the cross section for isolated large-p(T) prompt photon production in collisions of transversely polarized protons. We devise a simple method of dealing with the phase space integrals in dimensional regularization in the presence of the cos(2Phi) azimuthal-angular dependence occurring for transverse polarization. Our results allow us to calculate the double-spin asymmetry A(TT)(gamma) for this process at next-to-leading order accuracy, which may be used at BNL RHIC to measure the transversity parton distributions of the proton.
