• Emission spectra resulting from the reactions of He(2^3S), He^+, and He_2^+ with So_2, SOCl_2, SOBr_2, SO_2Cl_2, and SO_2FCl have been measured in a helium flowing afterglow in order to examine dissociative-ionization processes leading to SO^+(A^2Π_1). Although the SO^+(A^2Π_1-X^2Π_r) emission system was observed from the reactions of He^+ with SO_2, and So_2Cl_2, it was absent from those of He^+ with SOBr_2 and SO_2FCl. The vibrational distributions of SO^+(A) decreased nearly exponentially with increasing ν' for all the three reactions. The effective vibrational temperatures of SO^+(A) were determined to be 3320±230, 4620±760, and 3100±300 K for SO_2, SOCl_2, and SO_2Cl_2, respectively.
