Short Lived Species Produced in Pulse Irradiated Melts of LiF-KF and LiF-NaF-KF Eutectic Mixtures

For a long time, coloration in alkali halide melts containing the alkali metals (such as Li, Na) has received much attention in the study of the properties of excess electrons in ionic solutions(1). Today, there are evidences that the coloration is due to the formation of the solvated electron es- in the melts, whose existence is well known as a primary product of radiolysis of polar liquids such as water(2). Of more recent attention(3), alkali halide melts are a prospective stable material in molten salt nuclear reactor engineering in which melts are subjected to heavy irradiation by high energy nuclear radiation of different LET.
