Deuteron nuclear data for the design of accelerator-based neutron sources: Measurement, model analysis, evaluation, and application

Abstract

A comprehensive research program on deuteron nuclear data motivated by development of accelerator-based neutron sources is being executed. It is composed of measurements of neutron and gammaray yields and production cross sections, modelling of deuteron-induced reactions and code development, nuclear data evaluation and benchmark test, and its application to medical radioisotopes production. The goal of this program is to develop a state-of-the-art deuteron nuclear data library up to 200 MeV which will be useful for the design of future (d,xn) neutron sources. The current status and future plan are reviewed.

Development of a code system DEURACS for theoretical analysis and prediction of deuteron-induced reactions

“…DEURACS calculations reproduce well the experimental (d,xn) and (d,xd) data at the incident energies of 80 and around 100 MeV. Since we have confirmed that DEURACS is successfully applicable to deuteron-induced reactions, we plan to perform deuteron nuclear evaluation up to 200 MeV using DEURACS in the future [30].…”

Advanced breakup-nucleon enhancement of deuteron-induced reaction cross sections

“…The above-mentioned CDCC-Glauber-DWBA analysis, including the PE + CN components as above, of the (d, p) reaction also on 27 Al, 40 Ca, and 58 Ni [41] has reproduced also the experimental angular-distributions of the (d, p) reaction on 27 Al at 6, 12, and 23 MeV [71] as well as 27 Al(d, p) 28 Al excitation function from the threshold to 20 MeV. More recent DEURACS analysis of (d, x p) reactions on 27 Al at incident energies of 56 and 100 MeV [72] has reproduced fairly well the DDX data including both the NBU broad peak at half the incident energy, and the peak structure due to the stripping DR to bound states. The same approach has been proved successful for the account of 45 Sc(d, p) 46 Sc excitation function for incident energies up to 50 MeV.…”
