Abstract
Energy and angular distributions were measured for high-energy ( MeV) gamma rays from collisions of on Pb, Zn, and C at beam energies of MeV. The gamma-ray energy spectrum was measured to about 120 MeV at MeV and to about 80 MeV at MeV. For MeV the spectra are roughly exponential with characteristic slope parameters ranging from 10.0 MeV for + Pb at MeV to 14.2 MeV at MeV. Reasonable agreement is obtained with a model employing bremsstrahlung from individual neutron-proton collisions in the heavy-ion collision.
