“…The calculated efficiency value for sample source geometry ( ) and point source geometry ( p ) placed at 50 mm from the detector absorber are given in Table II with the correction factor (K C ) of coincidence summing effect. To calculate the efficiency of a particular γ-ray of the product radionuclide, we have used equation 2 which is a fitting function of interpolating the point-wise efficiencies (E γ ) of the γ-ray energy of the standard source 152 Eu [25,28].…”

In the present study we have measured the excitation functions for the nuclear reactions 100 Mo(α,n) 103 Ru, nat Mo(α,x) 97 Ru, nat Mo(α,x) 95 Ru, nat Mo(α,x) 96g Tc, nat Mo(α,x) 95g Tc and nat Mo(α,x) 94g Tc in the energy range 11-32 MeV. We have used the stacked foil activation technique followed by off-line gamma ray spectroscopy technique to measure the excitation functions. In this study we have also documented detailed uncertainty analysis for these nuclear reactions and their corresponding covariance matrix are also presented. The excitation functions are compared with the available experimental data from EXFOR data library and the theoretical prediction from TALYS nuclear reaction code. The present measurements are found to be consistent with the available experimental data.

The cross section values of the 71Ga(n,γ)72Ga reaction have been measured which are 9.14 ± 0.81 mb and 5.74 ± 0.50 mb at 2.15 and 3.19 MeV, respectively. The detail uncertainty propagation and covariance analysis are also given. The 7Li(p,n)7Be reaction was used to generate the neutrons and the neutron flux was normalised using the 115In(n,n’ )115Inm monitor reaction. The measured cross sectiondata are compared with the data available in the EXFOR database and with those of nuclear reaction model codes EMPIRE-3.2 and TALYS-1.95 and also with the evaluated nuclear data from ENDF/B-VIII.0 and JEFF-3.1/A. The comparison shows that our result at 3.19 MeV is in good agreement with those of EMPIRE-3.2 and JEFF-3.1/A. Since there are no other measurements available at 3.19 MeV, our data could not be compared with literature data at 3.19 MeV but it is consistent with the cross section values available at 2.98 ± 0.26 and 3.0 ± 0.1 MeV and our result at 2.15 MeV is slightly higher than the literature value available in EXFOR, evaluated value and theoretical predicted result.

Experimentally measured neutron activation cross sections are presented for the (n,α) , (n,α) , and (n,2n) reactions with detailed uncertainty propagation. The neutron cross sections were measured at an incident energy of 14.92 ± 0.02 MeV, and the neutrons were based on the t(d,n)α fusion reaction. The (n,α) reaction was used as a reference reaction for the normalization of the neutron flux. The pre-calibrated lead-shielded HPGe detector was used to detect the residues' γ-ray spectra. The data from the measured cross sections are compared to the previously measured cross sections from the EXFOR database, theoretically calculated cross sections using the TALYS and EMPIRE codes, and evaluated nuclear data.
