“…In Covariance analysis, the uncertainty propagation can be explained using the cross correlation between several observed values [32,33]. The method we have used to calculate the covariance matrix of the nuclear reaction in the present work is given in our previous article [22,34]. In the present experiment, we have used nat Ti(α, x) 51 Cr nuclear reaction as a monitor reaction.…”

The excitation functions of $^{66}$Ga, $^{67}$Ga, $^{65}$Zn and $^{64}$Cu radioisotopes produced via alpha-induced reaction on $^{nat}$Cu were measured using a stacked-foil activation method. The gamma-ray activity produced by the above-mentioned radionuclides was measured using the HPGe detector. The covariance analysis was performed to quantify the measured cross-section uncertainties as well as the correlation between different alpha energy cross sections. A covariance matrix and cross-sections for the $^{nat}$Cu($\alpha$,x)$^{66}$Ga, $^{nat}$Cu($\alpha$,x)$^{67}$Ga, $^{nat}$Cu($\alpha$,x)$^{65}$Zn and $^{nat}$Cu($\alpha$,x)$^{64}$Cu nuclear reactions in the projectile energy range of 15–37 MeV are reported in the present work. The measured reaction cross sections are compared with the existing experimental data and theoretically simulated results from the TALYS code.

“…The efficiency of a single crystal p-type HPGe detector was calibrated at various characteristic γ-ray energies using a standard 152 Eu point source (T 1/2 = 13.517 ± 0.009 y) of known activity (A 0 = 6614.71 ± 81.33 Bq as of 1 October 1999). The efficiency of the detector for the point source geometry was evaluated using the following equation given in [26,27] ( ) e = There are various sources of uncertainty in the calibration process, which generates uncertainty in the detectors efficiency. These uncertainties are from C, I, A 0 , and λ parameters respectively.…”

In the present work, we have measured 98Mo(n,γ)99Mo reaction cross section using a 7Li(p,n)7Be neutron source at 1.67 ± 0.14, 2.06 ± 0.14 and 2.66 ± 0.16 MeV neutron energies. We have employed offline γ-ray spectroscopy to measure the induced activity of the sample. The 115In(n,n’γ)115mIn reaction was used as a monitor reaction. Different attributes propagating the uncertainty in the total result, measured cross-sections with their uncertainties and correlation coefficients are given in detail in the present study. The result is compared with the data libraries, EXFOR database and theoretical model outcome from different level density models.

The evaluation and deduction of recommended cross section values allowing extension of the database to monitor energy and intensity parameters of charged particle beams is presented. Included are 53 charged particle (p, d, 3He, 4He) induced reactions on suited C, Al, Ti, Fe, Ni, Cu, Nb and Au targets. The new data allow more systematic simultaneous use of multiple reactions on the same target and promote the backings of electrodeposited and sedimented targets as monitoring aids. Where possible the energy range is extended to above 100 MeV. Integral yield curves over the studied energy range are derived and compared to experimentally measured yields at specific energy points. A comparison with the theoretical excitation curve prediction of the TALYS-code as available in the TENDL 2021–2023 libraries is shown.
