Isotope dependence of the breakdown strength of gases
Isotope dependence of the breakdown strength of gases
It has been found that while the highly nonuniform direct current breakdown voltages, V/sub s/, of H/sub 2/ and NH/sub 3/ exceed, respectively, those of D/sub 2/ and ND/sub 3/, the V/sub s/ of CH/sub 4/ is substantially lower than that of CD/sub 4/. The former (direct) isotope effect may be attributed to the higher ionization coefficients for the deuterated species compared with the nondeuterated, and the latter (inverse) isotope effect may result from differences in the electron-impact-induced dissociation processes of the isotopic pairs of molecules.
