Investigation of 54Fe(α, n)57Ni Reaction for Low Activation Material Fe

In fusion reactors, radioactivity can be controlled by effective material selection. Material selection is always important for efficient conversion of radioactivity to electrical energy.The selection of structural materials provides more efficient use of these structural materials with the results obtained from nuclear reactions. Low activation materials not only high in structural material performance and longer life, but also minimize related problems. Iron is an important element in fusion reactor technologies and astrophysical applications. For this reason, we obtained the theoretical cross-section values of the 54Fe(α, n)57Ni reaction in the range of 5-15 MeV (Mega electron volt) in this study. TALYS 1.8 (nuclear model code system) and NON-SMOKER (computer code) were used for theoretical calculations. Astrophysical S-factor values describing reactions at low energies were also calculated. In addition, reaction rate values were calculated with TALYS 1.8 and compared with EXFOR (experimental nuclear reaction data).

Excitation functions of some deuteron-induced nuclear reactions on Al

Excitation functions of the reactions 27Al(d,αp)24Na, 27Al(d,2p)27Mg and 27Al(d,p)28Al were measured by the activation technique up to deuteron energies of 37 MeV. The available experimental databases of the reaction products 27Mg and 28Al were extended and compared with the nuclear model calculations based on the code TALYS-1.8. Our measured data are reproduced well by the model calculations after adjustment of a few free input parameters. The cross-section ratio of the (d,αp) to (d,2p) process as a function of projectile energy was deduced from the measured data, and the result is interpreted in terms of competition between a proton and an α-particle emission.

Obtaining Astrophysical S-Factors and Half-Experimental Cross-Section Values for 121Sb (α, n) 124I Reaction

In this study, 121Sb (α, n) 124I reaction, which is one of the production reactions of the 124I radioisotope, which has an important use in nuclear medicine, was investigated. Experimental value EXFOR was obtained and theoretical data was obtained using TALYS 1.8 and NON-SMOKER half-experimental cross section values were calculated using theoretical data and experimental values. In addition, the Astrophysical S-factor was calculated. The obtained results were compared with EXFOR data.
