Abstract

The dose rate dependence of CF₂ Cl₂ decomposition was studied in both, gas and liquid phase, for the range of 2.95·10^{1 7}-1.9·10^{1 9} eV·g^-1·h^-1. The major products were found to be CF₃Cl, CFCl₃, CF₂Cl-CF₂Cl and CF₂Cl-CFCl₂. The decomposition of CF₂Cl₂ was found to decrease with decreasing dose rate for the liquid phase, while an opposite trend was found for gas phase radiolysis. A new mechanism which explains these contrasting findings was suggested. The contribution of radical and of ionic (or molecular) processes to the yields of the various products was estimated.
