Über den Kernrückstoß im kristallinen Hexachlorokomplex des vierwertigen Iridiums

Abstract

The Szilard-Chalmers reaction in crystals of Na2IrCl6 · 6 H2O, K2IrCl6, and (NH4) 2IrCl6 has been investigated by paper-electrophoresis. Several 192Ir-recoil species could be separated, their number and relative abundance being different for the three salts. E. g. in neutron irradiated Na2IrCl6 · 6 H2O six recoil species could be distinguished. On heating the crystals to 123°C the original substance is regenerated only by some of the fragments. The re-formation of the original compound (annealing) may be described by a first order reaction.
