Abstract
The D+D reactions are well known and widely used for a variety of purposes, mainly because of the use of the D(d , n )3 He reaction as a mono-energetic neutron source. The least studied of the D+D reactions is the D(d , n )pD reaction known as the deuteron breakup reaction, which produces a continuum of neutrons at energies below the monoenergetic peak. The neutron energy distribution as a function of angle for the cross section, , of the D(d ,n )pD reaction has been measured using a 6.94-MeV pulsed deuteron beam incident upon a D2 gas target. The time-of-flight technique was used to determine the energy of the neutrons detected in an array of two lithium glass scintillators and one NE-213 scintillator. The breakup cross section was determined as low as 225-keV neutron energy in the lithium glass detectors.
Highlights
Introduction and ExperimentThe D+D reactions yield mono-energetic neutrons from the D(d, n)3He reaction and a continuum of low-energy neutrons from the D(d, n)pD reaction for 7-MeV incident deuterons
The time-of-flight technique was used to determine the energy of the neutrons detected in an array of two lithium glass scintillators and one NE-213 scintillator
The D+D reaction yields mono-energetic neutrons up to approximately 8 MeV based upon the incident deuteron energy and yields breakup neutrons at lower energies
