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

摘要

A comparison of the yields of final products (~(57)Fe~(2+), ~(119)Sn~(2+)) of the transformation of M?ssbauer nuclei (~(57)Co, ~(119)Sn) 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 ~(57)Fe~(2+), ~(119)Sn~(2+), Ps, Mu, and H_2 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 H_2O~+, e~+, μ~+, Fe~(3+), and ~(119)Sn~(3+), respectively, is the most important process for understanding the formation of H_2, Ps, Mu, ~(57)Fe~(2+), and ~(119)Sn~(2+).
