摘要：

Double electron detachment cross sections for methane and nitric oxide negative ions passing through oxygen and nitrogen gas targets have been studied in the energy ranges of 2.0-10.0 keV for CH41 and 4.0-10.0 keV for NO-. The signal growth rate method was employed. Fragmentation was only observed for NO- anions colliding with both targets. In the case of CH4- anions no fragmentation was observed. The double electron detachment cross sections for methane ions is almost one order of magnitude larger than the one for nitric oxide ions. The fragmentation cross -sections for NO- is larger than the double electron detachment cross sections. (C) 2016 Elsevier B.V. All rights reserved.
