Neutrons and Gamma-Radiation from Deuteron Bombardment of Be

Neutron and gamma-ray intensities from thin targets of Be bombarded by deuterons were measured as a function of deuteron energy from 0.2 to 1.8 Mev. Most of the neutron data were obtained in the forward direction with respect to the deuteron beam. Neutron and gamma-ray intensities show exponential increase with energy below 800 kev; a broad resonance in the region 1.0 to 1.1 Mev is indicated by the shape of the curve at energies above 800 kev. Search revealed no sharp resonances. Evidence is shown for a previously unknown neutron group of $Q$ equal to -0.7 Mev. Neutron intensities were measured as a function of angle with the deuteron beam for a number of bombarding energies from 0.8 to 1.7 Mev.
