Abstract
We have so far developed a computational code system dedicated to deuteron-induced reactions in combination with some theoretical models. In our previous works, the code system was successfully applied to systematic analyses of double-differential cross sections (DDXs) of (d,xp ) reactions for 12 C, 27 Al, and 58 Ni at incident energies up to 100 MeV. In the present work, we apply the code system to neutron emission from deuteron-induced reactions. Since there is few experimental data of DDXs of (d,xn ) reactions, double-differential thick target neutron yields (TTNYs) are calculated and compared with experimental data instead of DDXs. The calculation using the code system reproduces the measured TTNYs for carbon at incident energies up to 50 MeV.
Highlights
In recent years, research and development of accelerator neutron sources has led to renewed interest in the study of deuteron-induced reactions
These results indicate that the stripping processes make a dominat contribution to neucleon emission in the whole incident energy range below 100 MeV and they should be taken into account using reliable theoretical models
A computational code system dedicated to deuteron-induced reactions has been applied to neutron emission in deuteron-induced reactions
Summary
Research and development of accelerator neutron sources has led to renewed interest in the study of deuteron-induced reactions. The (d,xn) reaction has strongly forward-peaked angular distribution, which is an additional advantage from the point of view of shielding From these favourable features, intensive neutron sources using deuteron accelerator have been proposed for various applications such as production of radioisotopes for medical use [3, 4] and irradiation testing of fusion reactor materials [5]. The calculation is in good agreement with the experimental data This result shows that the neutron stripping process to continuum is dominant in forward proton emission in the high incident energy region. Including the results of our previous works for the (d,xp) reactions, validation of the present modelling for both proton and neutron emissions from deuteron-induced reactions is discussed through comparison with available experimental data
