Abstract

Recoil iodine species produced by the system 123Xe → 123I are reacted with methane and ethane, both with and without additives being present, over the density range 10-4 to 0.5 g/cc. Qualitatively, major differences are observed between the behavior of methane and ethane. In methane the yield of organic products drops from ≃50 to ≃10%, while in ethane the yield increases over the same density range. The effects observed in the lower density region (10-4 to ≃10-1 g/cc) are interpreted in terms of an ion-molecule mechanism previously developed by us to explain the methane system at 1 atm. The trends observed at the higher densities are explained by the autoradiation hypothesis model.
