Abstract
Diffusion measurements have been made for Cl 2 in NaCl and RbCl crystals doped with OH - ions. Diffusion front was detected by observing the blue coloration with electron irradiation or the yellow fluorescence due to O 2 - ions. The solution of the diffusion equation with a chemical reaction permits the evaluations of diffusion coefficient and Henry's constant of Cl 2 in these crystals. Activation energies of the diffusion are 1.61±0.11 eV with D 0 =5.8×10 -5 m 2 s -1 in NaCl and 1.84±0.24 eV with D 0 =7.1×10 -2 m 2 s -1 in RbCl. These results are compared with theoretical results by Diller. Temperature dependence of the Henry's constant indicates that dissolution of Cl 2 molecules at the surface is the exothermic reaction.
