Abstract :
The method for characterizing neutrons produced by bombardment of beryllium with deuterons at energies from 3.0 to 7.0 MeV is discussed. Similar work for the characterization of the neutrons produced by the bombardment with protons from 2.0 to 4.0 MeV is presented. Both NE213 and lithium glass detectors were used in the time of flight measurement of the neutron spectra. The neutron spectrum from 27Al(d,n) was measured at 7.440 MeV deuteron energy and an angle of 120° with a 235U fission chamber.
