摘要：
The results of measurements in low temperature Ar+ dominated afterglow plasma are presented. The study was realized using Cryo-FALP apparatus operable in temperature range 77 - 300 K and at pressures 200 - 2000 Pa. We have observed decay of electron number density due to collisional radiative recombination (CRR). The measured ternary recombination rate coefficient of CRR of Ar+ ions with electrons and its temperature dependence are in good agreement with theoretical predictions of T-4.5 dependence.
