[en] Ion energy distributions and threshold energies are measured for the appearance of N2+ from N2. To our knowledge the same data are measured for the first time on O2+ from O2. For both ions a thermal peak is observed in the ion energy distribution having an onset at (61.1+/-0.5) eV and (60.5+/-0.8) eV for the N2+ ion and the O2+ ion respectively. The appearance energy of higher energetic ions is measured and interpreted.
