Abstract
High energy photons (up to 200 Mev) are emitted by various cyclotron targets when these are bombarded by protons with energies greater than 180 Mev. Spectral distributions, angular distributions, and yields are given for various proton energies and targets. Various possible origins are discussed in the light of the experimental observations.
