Measurements of Bremsstrahlung Spectra from 50 MeV Electrons on Ta and Photoneutrons Energy Distribution from Light, Medium and Heavy Nuclei

The results and methods of measuring the spectra of bremsstrahlung radiation from thick tantalum targets (H = 2 mm and H = 6 mm), produced by 50 MeV electrons are described as well as the measurement results for photoneutron spectra and yields front small samples of C, Al, Fe, Ni, Cu, Ta, Pb and 238U mounted in measured field of bremsstrahlung radiation. The theoretical analysis of the data was done.
