-The PI proposes to continue a research program with the PHENIX collaboration at Brookhaven National Lab using the Relativistic Heavy Ion Collider.  The proposed research seeks to determine the gluon contribution to the nucleon's spin by measuring the double longitudinal spin asymmetry of inclusive eta production by scattering polarized protons on polarized protons.  This work is complementary to measurements made with the pi-zero channel.  The PI predicts that measurements made in 2011, when combined with previous measurements, will be able to distinguish between a GSRV fit that assumes the maximum gluon polarization, however, the constraints on the standard GSRV fit may not be appreciable until the hadron's transverse momentum is much less than  than 4 GeV/c.  The PHENIX program in general will make substantial contributions constraining the polarized anti-up and -down quark distribution functions from Bjorken x between 0.1 and 0.4.
