Cross sections of some reactions of Ar, Ti, Ni, Cd and Pb with 14.1 MeV neutrons

Theoretical Calculations of the Cross-sections for (n,α) and (n,xα) reactions on the Structural Material for Fusion Reactor 46-50Ti

“…3). Nevertheless, the obtained cross-sections using the MLD-2 and the MLD-3 at 13-15 MeV incident neutron energy range are more consistent with the experimental data of [35], Yu and Gardner (1967) [26] and Cross and Pai (1963) [25]. At energy larger than 15MeV, the BSFGM is the best level density model for this reaction up to ~19.5 MeV incident neutron energy.…”

“…1-5. In addition, the results were compared with the available experimental data [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. The obtained excitation functions for 46-50 Ti (n, α) reactions using different level density models were very close to each other up to ~7 MeV, ~5 MeV, ~7 MeV, ~6 MeV and ~9 MeV incident neutron energies, and after this energy, different level densities indicate its influence on the cross-sections for these reactions (Figs.…”

Excitation Functions of 50Cr(n,np+pn+d)49V, 58Ni(n,α)55Fe, 58Ni(n,αp+pα)54Mn and 62Ni(n,α)59Fe Reactions

“…7). Most of the measurements were done at neutron energies around 14 MeV using different techniques (activation method [52,58,59], alpha-particle detection [47], mass spectrometry [48]). Our data agree with the value of Qaim and Molla [52] whereas the other data are slightly higher.…”

“…7.Excitation function of the '^Ni(n,a)^'Fe reaction. The low energy activation data of Qaim et al[8] were renormalized to IRDF-90.2 dosimetry file[20], The literature data around 14 MeV[47,48,52,58,59] were obtained using different techniques.…”

Cross-section measurement for the 206 Pb( n , α ) 203 Hg reaction induced by neutrons around 14 MeV

“…Therefore, the cross sections on lead which is an important fusion-reactor structural material isotopes induced by neutrons around 14 MeV are of special importance for the design, evaluation and construction of fusion reactors. The cross section for the 206 Pb(n, a) 203 Hg reaction induced by neutrons around 14 MeV has been measured at six laboratories [1][2][3][4][5][6], but these measurements differ by as much as a factor of 5-6 and four of them obtained data at only one energy [1,3,4,6], thus it is necessary to make further measurements to strengthen the reliability of the databases. In the present work, the cross section of the 206 Pb(n, a) 203 Hg reaction was measured in neutron energies of 13.5-14.7 MeV using the activation technique.…”
