Abstract : The variable-temperature flowing afterglow/Langmuir probe (VT-FALP) and the variable-temperature selected ion flow drift tube (VT-SIFDT) apparatuses have been exploited to study (i) dissociative electron attachment to HBr and HI and reverse processes of associative detachment of Br- and I- with H atoms (ii) secondary dissociative electron attachment reactions of the radicals CCl3 and CCl2Br formed in the primary dissociative electron attachment reactions of CCl4 and CCl3Br(iii) dissociative recombination reactions of several positive ion species (iv) the ternary association reactions of CH3+ ions with H2, N2 and CO as a function of the centre-of-mass interaction energy. Keywords: Electron attachment, Ion neutral reactions, Flowing afterglow, Plasma.
