Abstract

The energy and angular distributions of neutrons emitted from a thick target in the reaction 3H(d, n)4He were calculated using the Monte Carlo method based on the SRIM code. The first moments of the spectrum, namely mean neutron energy, energy spread and neutron yield, were determined at deuteron energies below 500 keV. The effect of the composition of the tritium target on the neutron spectrum was determined. The results obtained were compared with the available data.

Keywords
