Abstract

We have studied inclusive photon production from

π^{+} p

interactions at 10.5 GeV/c and found a source of centrally produced direct photons which accounts for (46±9)% of all photons detected with

{P_{L}}^{*}

and

P_{T}

between 0 and 20 MeV/c. The experimental data are found to be in good agreement with a calculation of hadronic inner bremsstrahlung.
