We report contributions to the nucleon spin and momentum from light quarkscalculated using dynamical domain wall fermions with pion masses down to 300MeV and fine lattice spacing a=0.084 fm. Albeit without disconnected diagrams,we observe that spin and orbital angular momenta of both u and d quarks areopposite, almost canceling in the case of the d quark, which agrees withprevious calculations using a mixed quark action. We also present the fullmomentum dependence of n=2 generalized form factors showing little variationwith the pion mass.
