Neutron production in the 120 MeV alpha particle bombardment of deuterium

Abstract

The neutron energy spectra from the α+d reaction at 120 MeV have been measured at eight angles. Time of flight and pulse height in an NE 218 liquid scintillator were recorded for each event. The resulting spectra were compared with quasi-elastic kinematic predictions. The location of high energy peaks in the 15°, 18°, and 21° spectra is slightly below that predicted by a "spectator proton" model. The pulse height response of the NE 218 scintillator to protons, deuterons, tritons, ³HE ions, and �HE ions is also reported.
