“…The resolution of the detector was also taken into account in the simulations by considering the energy resolution (FWHM) of the HPGe detector measured in the experiments. The broadening method of the MCNP Monte Carlo code [4,50,51] was used to propagate the energy resolution measured experimentally into the output of the Geant4 simulations. In this method, the deposited energy of each event in the detector (šø 0 ) is broadened by sampling from a Gaussian function whose mean value is šø 0 and the standard deviation is fitted from the experimental data as it will be reported in the results section.…”

“…High precision gamma-ray spectroscopy is a powerful tool that is widely used to study the structure of excited nuclear states [1,2] of irradiated targets in many applications such as prompt gamma neutron activation analysis [3][4][5] and proton induced prompt gamma emission [6][7][8][9]. The prompt gammarays produced by nuclear interactions between the target and the incident particles can be used for the determination and online monitoring of the elemental composition of the irradiated target.…”

“…The knowledge information available in the predictor variables is transferred from the input neurons to the hidden neurons via the weight, and then summed to get an estimate of the total stimulus of each hidden unit (Ozonoh et al 2020). The hidden neurons send the collected information to the output neuron through an activation function, generally the sigmoid (Shahabinejad et al 2020). Finally, the output neuron provides a response, then, compared to the desired value, and the error expected is calculated.…”

“…Sullivan et al [13] and Kamuda et al [14,15] presented an automated isotope algorithm in a large dataset of low-resolution gamma ray spectra containing a mixture of multiple radio-isotopes based on Bayesian and artificial neural networks respectively. Specifically, PGAA data have been analysed via applying machine-learning methods for detection of illicit materials [16,17] and online monitoring [18]. Recently, Kamuda et al [19] compared the performance of artificial neural networks and convolutional neural networks for automated gamma-ray spectroscopy to identify mixtures of radioisotopes.…”
