SCALP: Scintillating ionization chamber for ALPha particle production in neutron induced reactions

“…2) one can appreciate various discrepancies in the evaluated and experimental data, especially between 6 and 8 MeV. Data from Giorginis [11] and Khryachkov [12,13] are higher than the others data. In the range between 6 and 8 MeV also among the evaluations one can see important discrepancies.…”

“…Some nuclear data library about nuclear reaction cross section evaluations exist. The last three most important libraries about the 16 O(n,α) 13 For energies above 6 MeV (in Fig. 2) one can appreciate various discrepancies in the evaluated and experimental data, especially between 6 and 8 MeV.…”

“…It is possible to find in literature the works of Seitz and Huber [6], Davis et al [7], Divatia et al [8], Sekharan et al [9], Dandy et al [10], Giorginis et al [11] and Khryachkov et al [12,13]. The cross sections were estimated from the experimental values and nuclear model predictions.…”

“…In these conditions, the aim of the SCALP project is then to perform several measurements of the 16 O(n,α) 13 C cross section up to 10 MeV and with an accuracy which will be improved in the progressive work. The experiment is based on the detection of the α-particles produced in the reaction.…”

“…Since 2014 the CIELO Pilot Project [5] was devoted to improve the nuclear evaluations. The knowledge of the 16 O(n,α) 13 C cross section from the reaction threshold (2.36 MeV) to at least 10 MeV with a great accuracy is a major goal for the nuclear and the reactor physics. a e-mail: galhaut@lpccaen.in2p3.fr; bastien.galhaut@ eamea.fr…”
