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

Abstract

The cross-section data of the 85Rb(n, 2n)84Rb reaction have been measured with the neutron energies of 12 MeV to 19.8 MeV using the activation technique and the relative method. The 85Rb samples were irradiated on the surface of a two-ring orientation assembly with neutrons produced from the 3H(d, n)4He reaction at the 5SDH-2 1.7-MV Tandem accelerator in China. Theoretical model calculations were performed with the TALYS-1.9 code. The present data were compared with previously obtained experimental data and the available evaluated data.

Measurement of 169Tm(n, 2n)168Tm reaction cross sections from 12 to 19.8 MeV*

“…Measured cross sections. The present data gave a peak around16 MeV. The experimental data from Bayhurst et al[4] were approximately 6% higher than the present ones between 16 and 17 MeV and were in agreement with the present data from 19 to 20 MeV.…”

“…There are obvious discrepancies among these experimental data, especially at incident energies of 13 to 18 MeV. There are also discrepancies among the evaluated data from ENDF/B-VIII.0 [14], JENDL-4.0 [15], and JEFF-3.3 [16] in the energy range 12-20 MeV. In particular, data from JEFF-3.3 are approximately 10%−20% lower than those from ENDF/B-VIII.0 and JENDL-4.0 between 16 and 20 MeV.…”

Cross-sections for , and reactions on molybdenum isotopes in the neutron energy range of 13 to 15 MeV *

“…The radioactive products were identified to measure the cross sections of nuclear reactions. The detailed procedure is available from published works [81][82][83][84][85]. Only a few salient characteristics associated with our measurements are presented in this report.…”

Cross-section measurements of (n, 2n) and (n, p) reactions on 124,126,128,130,131,132Xe in the 14 MeV region and theoretical calculations of their excitation functions *

“…3, in the former figure, the weaker 132 I γ-ray transitions at 522.65 keV are also indicated. The ORTEC® GammaVision® Gamma Spectrum Analysis computer program examined the peak area [26] using the emulation package of OR-TEC® MAESTRO® MCA for data collection and analysis [26].…”
