The decomposition of metastable positive ions of methane formed by electron bombardment is discussed. Some new collision‐induced decompositions involving the formation of H + , H 2 + ˙ and H 3 + have been found in the ion kinetic energy spectrum as well as in the mass spectrum of methane. In the latter case, the ‘metastable peaks’ occur below mass 1 on the mass scale and can be used for mass calibration in this region of the mass spectrum.
