We derive the partonic level longitudinal spin-spin asymmetries for the processes relevant to the hadronic production of isolated double photon events, specifically qq» and gg. We discuss production rates and observable asymmetries (ALL) in polarized pp collisions at the BNL Relativistic Heavy Ion Collider and their dependence on the spin-dependent sea and gluon distributions. Because the decay H0 is a possibly important signal for intermediate mass Higgs-scalar production, we also briefly discuss the spin dependence of standard model Higgs-boson production via ggH0(lowPT) and gggH0, qgqH0, and qq»gH0(highPT).
