A Study on the New Empirical Cross Section Formulae for (gamma, p) Reactions at 20 +/- 1 MeV Incident Energy

Abstract

WOS: 000444828500007In this study, we have investigated theoretical cross sections of (gamma, p) reactions at 20 +/- 1 MeV for the photon incident energy and then we have obtained two new empirical formulae for 40 <= A <= 108 and for the even Z-even N target nuclei including new fitting parameters. These new empirical formulae depending on the asymmetry parameters (s = (N - Z)/A) were determined by using the least squares approximation fitting method to the available experimental cross section data taken from EXFOR. The results have been compared with the experimental data and found to be well in agreement.Osmaniye Korkut Ata University's Scientific Research Office (BAP) [OKUBAP-2018-PT3-09]; Kahramanmaras Sutcu Imam University Scientific Research Office (BAP) [2018/3-28M]This work is supported by the coordinator ship of Osmaniye Korkut Ata University's Scientific Research Office (BAP) with contract no: OKUBAP-2018-PT3-09 and Kahramanmaras Sutcu Imam University Scientific Research Office (BAP) with contract no: 2018/3-28M
