The simultaneous diffusion of Ar 41 and Kr 85m into single crystals containing 30 mole percent of KCl and 70 mole percent of RbCl is studied. The rare‐gases are created by irradiation with fast neutrons. The diffusion kinetics are similar to those of the systems KCl/Ar and RbCl/Kr. The interesting high temperature region is characterized by activation energies of (0.28 ± 0.035) eV and (0.56 ± 0.035) eV for KCl—RbCl/Ar and KCl—RbCl/Kr, respectively. The diffusion coefficients of argon are about one order of magnitude higher than those of krypton. Comparison with experiments performed after irradiation to high neutron doses shows that these values are not affected by radiation damage.
