Abstract
The cross-sections of the electron impact dissociative ionization of m ethane have been measured for electron energies from threshold to 100 eV. For CH4+ the results agree with the existing measurements. For the fragments of CH3+, CH2+, CH+, and C+, our results overlap with the pr evious results within their reported error limits. These earlier measu rements exceed their given error limits and hence are inconsistent. At higher backing pressures the subsequent ion-molecule reactions and th eir product ions have been measured.
