Resemblance of intratrack processes as a common starting point of radiation chemistry and positron, muon, and Mössbauer spectroscopies

Abstract

A comparison of the yields of final products (57Fe2+, 119Sn2+) of the transformation of Mossbauer nuclei (57Co, 119Sn) in frozen aqueous and alcoholic glassy solutions with the Ps, Ms, and radiolytic-hydrogen formation probabilities in the same liquid media subjected to irradiation with positrons, muons, and fast electrons, respectively shows that the yields of 57Fe2+, 119Sn2+, Ps, Mu, and H2 vary in similar manners with a change in the concentration of electron scavengers or the temperature of the medium. These correlations are a manifestation of a profound similarity between the primary processes occurring in ionizing-particle tracks. Obviously, the recombination of ion-electron pairs inside large swarms (blobs) involving H2O+, e+, μ+, Fe3+, and 119Sn3+, respectively, is the most important process for understanding the formation of H2, Ps, Mu, 57Fe2+, and 119Sn2+.
