Trends in (n,γ) reaction with atomic number(6 to 109) for most abundant isotope of each element using TALYS and EXFOR

In the present work the study on the variation of the trend of the cross-section of the radiative neutron capture reaction for the most abundant isotope of an element of atomic number in the range 6 to 109 with mass varying from 12 to 268 was observed. The values of cross-sections were obtained at 14 MeV neutron energy using the nuclear code TALYS. Further, for the elements from atomic number 110 to 118, no calculations were carried out as the parameters required for the same are yet to be incorporated in the code. The corresponding available experimental data, if any, was also studied using the EXFOR database. For (n,p), (n,alpha) etc. reactions, the number of experimental values are higher compared to (n,gamma) reaction. The radiative neutron capture is important for neutron balance and now for breeding in nuclear reactors as this reaction gives rise to heavy unstable nuclei which may decay into a fissile material. A general trend of variation of (n,g) cross-section with incident neutron energy for ²³⁸U isotope is given
