The presented work focuses on study of electron - positive ion recombination in low temperature plasma. The principal method used were Flowing afterglow with Langmuir probe and Stationary afterglow with Cavity Ring-Down Spectrometer. For the first time electron and neutral assisted collisional radiative recombination of Ar+ ions was studied in temperature range of 50 - 200 K. Resulting ternary recombination rate coefficients are in good agreement with theoretical predictions. Recombination of H3 + and D3 + ions with electrons was studied in the temperature range of 50 - 300 K and binary and ternary recombination rate coefficients were obtained. The effect of nuclear spin on recombination of H3 + ions with electrons was studied in the temperature range of 80 - 200 K and state selective recombination rate coefficients were obtained for ortho- and para-H3 + . Results show that at 80 K para-H3 + recombines with electrons substantially faster than ortho-H3 + .
