Cross-section measurement of (n,2n) reactions for Nd isotopes induced by 14 MeV neutrons

Cross section measurements on zirconium isotopes for ~14 MeV neutrons and their theoretical calculations of excitation functions *

“…At the neutron energies of 13.5 and 14.1 MeV, our experimental values are in agreement, within the experimental error, with those of theoretical excitation curve obtained by Talys-1.9 at the corresponding energies. The cross sections of Molla et al [15] and Begun et al [24] are higher than that of the fitted line of our experimental values and that of theoretical excitation curve obtained by Talys-1.9 at the corresponding energy. The theoretical excitation curve matches these experimental data well in general.…”

“…2-9 for comparison. Different parameters in the theoretical model program system Talys-1.9 were set according to our experimental cross sections and the results in previously published works [2][3][4][5][6][13][14][15][16][17][18][19][20][21][22][23][24] for different nuclear reactions. For example, the optical model potential (OMP) parameter r V was set for the 96 Zr(n,γ) 97 Zr, 96 Zr(n,2n) 95 Zr, and 90 Zr(n,α) 87m Sr reactions, the OMP parameter r V and a V were set for the 94 Zr(n,d*) 93m+g Y, 94 Zr(n,α) 91 Sr, and 92 Zr(n,p) 92 Y reactions, the OMP parameter r V , a V and the level density parameter at the neutron separation energy were set for the 94 Zr(n,p) 94 Y reaction, the OMP parameter r V , a V , model for level densities and the overall constant for the matrix element or the optical model strength in the exciton model were set for the 90 Zr(n,p) 90m Y reaction.…”

Measurement of 85Rb (n, 2n) 84Rb reaction cross-section from 12 MeV up to 19.8 MeV *

“…The method of the activation technique is the same as Refs. [9,10]. The cross-section data for the 85 Rb(n, 2n) 84 Rb reaction were measured within the neutron energies of 12 MeV to 19.8 MeV and compared with the previous experimental data and available evaluated data.…”
