  We investigate the generalized form factors of the nucleon in a light-cone
spectator-diquark model. Compared to the form factors, the generalized form
factors contain some more information of the structure of the nucleon. In our
calculation, both the scalar and the axial-vector spectator-diquark are taken
into account. As a relation between the spin in the instant form and that in
the light-cone form, the Melosh-Wigner rotation effect is included for both the
quark and the axial-vector diquark. We also provide numerical results from our
model calculations, and the results are comparable with those from lattice QCD.
