SPECTRA OF NEUTRONS FROM THE REACTIONS LI-6(D,N-ALPHA)HE-3 AND BE-9(D,N)B-10 AT DEUTERON ENERGIES UP TO 2.0 MEV

Spectra of neutrons from the reactions Li-6(d, n alpha)He-3 and Be-9(d , n)B-10 are measured by the time-of-flight method. Continuous spectra from the first reaction are obtained at deuteron energies E(d) = 1.1 and 2.0 MeV for five angles in the range 10 degrees - 130 degrees; the energy threshold of neutron detection is found to be 0.2 MeV. Line sp ectra in the second reaction are measured at E(d) = 0.5, 1.0, 1.5 and 2.0 MeV for nine angles in the range 0 degrees - 165 degrees for the g round state and the first six excited states of B-10. Differential and total effective cross sections for neutron production are determined for the two reactions. Special features of the spectra and possible me chanisms of the processes under consideration are discussed.
