We have derived a transition amplitude for resonant transfer and excitation (RTE) in a crystal channel. Here we present results of a comparison with the recent observations of Belkacem et al. of titanium ions channeled in a thin gold crystal [A. Belkacem et al., Phys. Rev. Lett. 64 (1990) 380]. We introduce a 1D tight-binding model of the gold lattice to represent the crystal's periodicity and to connect with an electron's momentum profile in atomic gold. We find, with approximation, that the RTE cross section is proportional to the Compton profile of atomic gold times a crystal-structure factor. Our results are analogous to multislit interference of light with diffraction. Because of the narrowness of the 6s and 5d Compton profiles in gold, Belkacem et al. observed the principal maximum with a very narrow width determined by the crystal's Fermi energy. Unlike the observations however, we predict no shift in the RTE peak other than about 6 eV from the crystal's work function.
