PRODUCTION OF POSITIVE IONS AND ELECTRONS IN COLLISIONS OF 1-25 keV PROTONS AND HYDROGEN ATOMS WITH CO, CO2, CH4, AND NH3,

Abstract

Cross sections are reported for the production of slow, positive-ions (sigma(+)) and electrons (sigma(-)) in collisions of 1-25 keV protons and hydrogen atoms with CO, CO2, CH4, and NH3. For H(+) bombardment sigma(-) is the total ionization cross section, and sigma(+) - sigma(-) is the total electron capture cross section, sigma 10. For H(o) bombardment sigma(+) is a good approximation to the total ionization cross section. The results are compared with other results in different, overlapping energy ranges, and their application to the physics of planetary atmospheres is discussed. (Author)
