【Abstract】 In previous paper[1] We reported that dichlorofluoromethane is a promising compound for laser enrichment deuterium. In this work soma parametric effects（such as wavelength, fluence, total and partial pressure of deuterium compound）were measured experimentally and the quantum yield was calculated from experimental data. We have found the dissociation rate of CFDCl2 is rather dependent on total pressure than on partial pressure of CFDCl₂ Whereas the enrichment factor does not depend on Ptotal but strongly on PCFDCl₂· A critical pressure of PCFDCl₂ was found, above which the reaction is nonisotopic selective The possible mechanism of nonselective reaction was discussed.更多还原
