Nonperturbative approach to the direct photon spectrum nearx=1in the inclusive radiative decay ofJψ

A Born-approximation calculation of the direct photon spectrum for {ital x}{approx lt}1 in the inclusive decay {ital J}/{psi}{r arrow}{gamma}+hadrons is given in the framework of the QCD multipole expansion in which bound-state contributions to the intermediate states are taken into account. The obtained photon spectrum in the {ital x}{approx lt}1 region is quite close to the experimental data.
