Abstract

The recombination of HCO+ ions with electrons was studied in the temperature range of 80–200 K using a combination of stationary afterglow with CRDS and microwave diagnostic techniques. The determined recombination rate coefficient is αHCO+=(1.32±0.14)(300K/T)(0.52±0.14)×10−7 cm3 s−1. The pressure broadening coefficients for the P(4) transition of the 2000 ← 0000 vibrational band of HCO+ and the upper estimates for the reaction rate coefficient for the (HCO)+·CO cluster formation assisted by helium were also obtained.
