Abstract
We analyze the quark mass dependence of photon gluon fusion in polarized de ep inelastic scattering for both the intrinsic and extrinsic gluon distribu tions of the nucleon. We calculate the effective number of flavors for each of the heavy and light quark photon gluon fusion contributions to the firs t moment of the spin-dependent structure function g(1)(x).
