The mechanism of the formation of “molecular” hydrogen in the ethane radiolysis at 300 Torr has been studied with ethane-ethane-d6-ethylene mixtures. The G-value of the hydrogen has been found to be 3.3. The addition of electron and positive ion scavengers scarcely affected the formation of the hydrogen at all. From the isotopic composition of the hydrogen, it was demonstrated that most of the hydrogen is formed by molecular detachment from the ethane molecule, while the rest is formed by the abstraction of a hydrogen atom from the ethane molecule by a hot hydrogen atom, the G-value being estimated to be 0.6.
