A study on the estimations of (n,t) reaction cross-sections at 14.5 MeV by using artificial neural network

Abstract

In this paper, calculations of the [Formula: see text] reaction cross-sections at 14.5 MeV have been presented by utilizing artificial neural network algorithms (ANNs). The systematics are based on the account for the non-equilibrium reaction mechanism and the corresponding analytical formulas of the pre-equilibrium exciton model. Experimental results, obtained from the EXFOR database, have been used to train the ANN with the Levenberg–Marquardt (LM) algorithm which is a feed-forward algorithm and is considered one of the well-known and most effective methods in neural networks. The Regression [Formula: see text] values for the ANN estimation have been determined as 0.9998, 0.9927 and 0.9895 for training, testing and for all process. The [Formula: see text] reaction cross-sections have been reproduced with the TALYS 1.95 and the EMPIRE 3.2 codes. In summary, it has been demonstrated that the ANN algorithms can be used to calculate the [Formula: see text] reaction cross-section with the semi-empirical systematics.

Analysis of Double Differential Cross Section for Neutron Induced and Neutron Emission Reaction of 209Bi Isotope

“…TheKalbach-Mann systematics (Kalbach and Mann, 1981;Kalbach, 1982) arepreferred for DDX calculations in the code because of play an important role in the pre-equilibrium reaction studies.For compound and direct processes, Hauser-Feshbach,exciton model, and optical model parameters are used (Hauser and Feshbach, 1952;Koning and Delaroche, 2003). There are many theoretical studies (Yiğit, 2021;Özdoğan et al, 2021a;Sadeghi et al, 2010;Kara et al, 2021;Şekerci et al, 2020;Kaplan et al, 2015;Kaplan et al, 2013;Özdoğan, 2021;Küçüksucu et al, 2022;Özdoğan et al, 2021b;Canbula, 2021;Canbula, 2017;Canbula, 2020) using Talys computer code for neutron induced or neutron emission nuclear reactions in the literature.…”

Investigation of the Effects of Optical Models on the Production Cross–Section Calculations of 22,24Na Radioisotopes with some (d,x) and (α,x) Reactions

“…Many factors, which may differ depending on the investigated topic, such as technological and physical infrastructure, financial capacity, and trained manpower, are critical to the effective completion of experimental research. In the event that an experimental study, which have to be designed by combining these and many other possible factors in a functional way, cannot be realized, the way for researchers to have a foresight on the subject they are examining can be obtained from theoretical studies and computer-aided simulations [4][5][6][7][8][9][10][11][12][13]. An essential consideration here is that the involvement of a theoretical basis is required in both circumstances, whether an experimental research or computer-aided modeling study.…”
