“…helium production cross sections near 10 and 15 MeV,14,15 and with charged-particleemission measurements. [16][17][18][19] As found in the 58Ni case, the ENDF/B-VI evaluation for 6%i overestimates the cross section from threshold to about 14 MeV where it was constrained by measured values. The disagreement with our data can be as large as 75%.…”

Neutron-induced reactions producing light charged particles continue to be investigated at the spallation fast-neutron source at the Los Alamos Neutron Science Center (LANSCE). New dah on the cross seclions for alpha-parlicle produclion for neukons on 5*Ni and a N i are presented from threshold to 50 MeV. Recent changes in the experiment now allow protons, deuterons, tritons, 3He and alpha particles to be identified.

“…This reduction is rather similar to that found necessary for the target nuclei 59 Co, and 58,60,62 Ni [2], so that it has been taken into account also for 55 Mn. Lastly, the calculation of the deuteron transmission coefficients has been carried out by using the global OMP of Lohr and Haeberli [47] and validated throughout analysis of the deuteron-emission spectra at 14.8 MeV [48].…”

“…While the measured particle spectra of Ref. [48] are given in the laboratory system, their conversion to the center-of-mass system is equivalent to a shift of the spectrum to higher energies, of up to one MeV for the most energetic α-particles (see, e.g., Refs. [65,66]).…”

Excitation functions were measured for the 55 Mn(n,2n) 54 Mn, 55 Mn(n,α) 52 V, 63 Cu(n,α) 60 Co, 65 Cu(n,2n) 64 Cu, and 65 Cu(n,p) 65 Ni reactions from 13.47 to 14.83 MeV. The experimental cross sections are compared with the results of calculations including all activation channels for the stable isotopes of Mn and Cu, for neutron incident energies up to 50 MeV. Within the energy range up to 20 MeV the model calculations are most sensitive to the parameters related to nuclei in the early stages of the reaction, while the model assumptions are better established by analysis of the data in the energy range 20-40 MeV. While the present analysis has taken advantage of both a new set of accurate measured cross sections around 14 MeV and the larger data basis fortunately available between 20 and 40 MeV for the Mn and Cu isotopes, the need of additional measurements below as well as above 40 MeV is pointed out.

“…The optimum incident neutron energy range for producing the 65 Ni nucleus is 12 to 13 MeV by using TALYS [4] and 13 to 14 MeV by using EMPIRE [2]. The maximum cross-section values are obtained by ∼13 MeV in both codes, and the results using the BSFG Model [13] of TALYS [4] are closer to experiment [25] than those Comparison between calculated total cross section with G.C level density [11], BSFG [14] and Fermi Gas Model nuclear level density (continuous and dashed lines) for 65 Cu(n, xp) reaction to the experimental data [19,22,23] in neutron energy range from 9.0 to 15.0 MeV using the Exciton Model.…”

Abstract.Copper is one of the constituents of alloys for structural components and a dosimetry material. In this study, we calculated the proton emission spectra and the excitation function produced by (n, xp) and (n, p) reactions respectively by using the Exciton model predictions combined with the Kalbach angular distribution systematics and the Hybrid Monte-Carlo Simulation (HMS). The sensitivity studies on the input parameters from optical model, level density, spin cut-off parameter and mean free path have been investigated for our calculations with the code EMPIRE and the code TALYS. The proton emission spectra and the excitation function for 65 Cu nucleus were discussed and found in good agreement with the available experimental data.
