“…The experimental data are taken from Refs. [22][23][24][25][26][27]. In the wide incident energy range, the present calculation reproduces both the shape and magnitude of the experimental TTNY spectra at forward angles around 0 o .…”

Abstract.We have so far developed a computational code system dedicated to deuteroninduced 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.

“…Energy-integrated thick target neutron yields at 0° are shown in Figure 8 along with other experimental data [1,[7][8][9][10]. In the energy integration, the experimental yields below 1 MeV corresponding to the lowest measured energy were supplemented by linear extrapolation with the data at 1 MeV.…”

Double differential neutron yields from carbon target irradiated by 5 MeV and 9 MeV deuterons were measured at the Kyushu University Tandem Accelerator Laboratory. A carbon target was thick enough to stop the incident deuterons in the target. An NE213 liquid organic scintillator was employed to detect neutrons emitted from the target and placed at several directions from 0° to 140°. To estimate the contribution of scattered neutrons from the floor and walls, neutron yields were measured with an iron shadow bar located in front of the scintillator. The measured energy spectrum was derived by an unfolding method with FORIST and MAXED codes using the response functions of the NE213 scintillator calculated with the SCINFUL-QMD code. The incident energy dependence of total thick target neutron yields for carbon was investigated over the energy range from 5 to 50 MeV and the empirical formula was obtained. The measured neutron energy spectra were also compared with the calculations by PHITS code.

“…Thus the formulas that result are [14] and Saltmarsh, et al [7] The calculat1ons are lower. than the measurements of Lone, et al, [10] and '-leaver, et al, [12] but higher than those of Goland et al It should be noted that the data of Lone, et al, show a very large yield for low energy neutrons (E < 2), which is very uncertain due'to uncertainties in detect~on efficiency. If the 2.3 MeV detection threshold of Lone, et al, is used instead of their 0.3 MeV threshold, the C/E's change to .89, .92, .85 respectively.…”
