Abstract: (APS)

A Born-approximation calculation of the direct photon spectrum for x≲1 in the inclusive decay Jψ→γ+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 x≲1 region is quite close to the experimental data.
