Abstract
IN a recent investigation of the ionisation processes in methane, Hogness and Kvalnes (Phys. Rev., 32, December 1928), using a mass-spectrograph method, find that at 14.5 volts only CH4+ ions are formed, but at 15.5 volts two processes occur; either stable CH4+ ions are formed or unstable CH4+ ions which dissociate spontaneously into CH3+ ions and neutral hydrogen atoms, the probabilities of the processes occurring being approximately equal over a wide range of pressure.
