Recombination of O2+ ions by electron capture from atomic hydrogen in photo-ionized nebulae.

HONVAULT P., GARGAUD M., BACCHUS-MONTABONEL M.-C. and McCARROLL R.

Abstract (from CDS):

Detailed calculations are presented of cross sections and rate coefficients at thermal energies for electron capture by 3P ground state O2+ ions from atomic hydrogen. The rate coefficient remains practically constant, between 1.1 and 1.2x10–9cm3/s in the temperature range from 200 to 20000K. The rate coefficient for electron capture by O2+ to ions in the metastable 1D or 1S states is negligible at temperatures less than 106K.
