Measurements of (n,xp), (n,xd) Double Differential Cross Sections of Carbon and Aluminum for 65 and 75 MeV Neutrons

Abstract

Double differential (n, xp), (n, xd) cross sections of carbon and aluminum were measured for 65 and 75 MeV neutrons at angles between 12° and 70° using L::.E-E telescopes at a 7 Li(p, n) neutron source facility at TIARA. The data at 12° were obtained by employing an annular geometry. The telescopes consisting of SSD and NaI(Tl) scintillator, experimental methods and the data reduction procedures are presented as well as the results. The carbon data are compared favorably with existing experimental data. The (n, xp) spectra of both carbon and aluminum agreed fairly well with theoretical calculations based on the intra-nuclear cascade model and the multi-step Hauser-Feshbach model including preequilibrium effects, but the (n, xd) spectra differ significantly from those calculations.

Nuclear data for radiotherapy: Presentation of a new ICRU report and IAEA initiatives

“…The present work represents an advance over these earlier approaches principally in two ways: (1) it makes use of recent improvements in nuclear model calculations and optimizes them for describing nuclear reactions in the 0 to 250 MeV energy region; and (2) new experimental information, which has become available since the earlier studies, is used extensively to guide the calculations. Perhaps the most important measurements of non elastic processes are the neutron cross section measurements by Benck et al [2], Haight et al [14], Nauchi et al [22], Slypen et al [27,28] and Subramanian et al, [29,30] and and the proton cross section measurements by Bertrand et al [3], Cowley [tl], F6rtsch et al [13] and Meier et al [18,19].…”

Measurement of differential cross sections of neutron-induced deuteron production reactions on carbon from 25 to 52 MeV *

“…9 and the tabulated data are given in Table 2. Brenner 's theoretical calculations using INCA code [16,19] are also included in Fig. 9.…”

“…To compare the results from the present work with the previous ones from the literature [9,13,[16][17][18] and the data from theoretical calculations [19], differential cross sections of the 12 C(n, xd) reactions are obtained using the measured data R(θ L , E n ) and the evaluated n-p scattering differential cross sections from the JENDL-4.0/HE-2015 library for normalization [22], as described in Eq. (2).…”

Neutron, proton, and photonuclear cross-sections for radiation therapy and radiation protection

“…We also made use of neutron total non-elastic cross section measurements compiled by the NNDC [13]. Charged-particle production spectra have been particularly important for guiding and testing the calculations, principally the measurements from the University of California at Davis [17,18], Los Alamos [19], Louvain-la-Neuve [20][21][22] and Tohoku University [23].…”
