Measurements of the cross sections of the ~(186)W(n,γ )~(187)W, ~(182)W(n, p)~(182)Ta, ~(154)Gd(n,2n)~(153)Gd, and ~ (160)Gd(n,2n)~(159)Gd reactions at neutron energies of 5 to 17 MeV

摘要

The cross sections of the ~(186)W(n,γ )~(187)W, ~(183)W(n,p)~(183)Ta and ~(154)Gd(n,2n)~(153)Gd, ~(160)Gd(n,2n)~(159)Gd reactions were measured at the neutron energies 5.08 ± 0.165, 8.96 ± 0.77, 12.47 ± 0.825, and 16.63 ± 0.95 MeV. Standard neutron activation analysis technique and off-line γ ray spectrometry were used for themeasurement and analysis of the data. Measurements were done in the energy range where few or no measured data are available. The results from the present work are compared with the literature data based on the EXFOR compilation. The experimental results are supported by theoretical predictions using nuclear modular codes TALYS 1.8 and EMPIRE 3.2.2. The predictability of different one-dimensional models available in TALYS 1.8 and Levden models in EMPIRE 3.2.2 were tested.Adetailed comparison of experimental results with theoretical model calculations is made.
