Ternary Recombination in Helium Plasma
Original language description
A study of ternary recombination of He2+ ions with electrons was carried out using flowing afterglow apparatus equipped with axially movable Langmuir probe (FALP). The flow tube was cooled down to 77 K and the number density of helium buffer gas was varied in the range of $1times 10^{17} cm^{-3}$ - $5times 10^{17} cm^{-3}$. At these conditions, there are three main processes of recombination - dissociative recombination, ternary recombination (helium assisted) and collisional radiative recombination -CRR (the third particle is an electron). We observed the dependence of effective recombination rate coefficient alfaeff on helium buffer gas density with the ternary rate coefficient $K_He = (9.0 pm 3.0)times 10^{-26} cm^6s^{-1}$ while the extrapolation of this dependence towards low helium density gives the value of ternary recombination rate coefficient of CRR of He2+ ions with electrons $K_{CRR}=(2,2pm0.8)times10^{-17}cm^6s^{-1}$. These results are in good agreement with theoreti
