A method is described for the amplitude-time selection of pulses for the study of the interaction of fast neutrons from the D(T, d)He/sup 4/ reaction with atomic nuclei. Employing as detectors of neutrons and alpha -particles stilbene crystals and photomultipliers FEU-33, a time resolution of 1 nsec and an energetic resolution of 7 per cent were attained. The developed method was applied for measurement of the differential sections of elastic scattering of 14 Mev neutrons on bismuth over a range of angles of 20 to 115 deg . The experimental results are corrected for error due to finite geometry and the configuration of the initial neutron beam, and are compared with the theoretical curve constructed on the basis of the optical model of a nucleus with potential proposed by Bjorklund and others.
