Abstract
A set of early chemical reactions induced in frozen medium around decayed 57Co or 119mSn nuclei by emitted Auger electrons is suggested. The mechanism predicts a correlation between formation probabilities of final products, namely Fe2+-Fe3+ or Sn2+-Sn4+ ions, positronium atom and molecular hydrogen formed in similar medium after its irradiation by fast positrons and electrons. This correlation indicates a similarity of chemical processes occurring in nanovolumes around Mossbauer 57Fe- and 119Sn-nuclei after radioactive decay as well as in tracks produced by fast positrons and electrons. The important role of quasi-free electrons is revealed.
