Description
Iron-based alloys are important construction materials which are widely used in science and industry. Information about cross-sections of different nuclear reactions on iron is needed to accurate modeling of different nuclear facilities, elemental analysis and other applications. From theoretical point of view, experimental cross-sections are needed to ajust optical potentials for incoming and outgoing particles.
Measurements of the $\gamma$ ray emission cross-sections in Fe($n,x\gamma$) were performed using TANGRA facility with high-purity germanium (HPGe) detector[1]. Neutron generator ING-27 with embedded 64-pixel $\alpha$-detector was used as 14.1 MeV neutron source. In this experiment 17 $\gamma$-transitions were observed; for 13 $\gamma$-transitions cross-sections were measured and compared with data obtained in other experiments and results of calculations in TALYS. Data processing procedure and discrepancy between our results and previous measurements[2-5] will be discussed.
