Emission spectrum resulting from the energy transfer reaction of He (2 /sup 3/S) with transient CS radical produced through a microwave discharge of Ar/CS/sub 2/ mixture was observed in a flowing afterglow apparatus. A new CS/sup +/ (B /sup 2/..sigma../sup +/--X /sup 2/..sigma../sup +/) band system due to He (2 /sup 3/S)/CS Penning ionization was identified in the 220--340 nm region. The dominant bands were the (..nu..',0) and (0, ..nu..'') progressions, which was consistent with the prediction from calculated Morse potential Franck--Condon factors. Although the observed bandhead wavelengths of the major CS/sup +/ (B--X) emission were in good agreement with those predicted from the reported spectroscopic data, the (4,0) band was located at an abnormal position. It was interpreted as a consequence of vibrational perturbation in the B /sup 2/..sigma../sup +/ state. The relative intensities of CS/sup +/(B--X), CS/sup +/(B--A), CI, and SI emission were estimated to represent that the dominant pathway of the He (2 /sup 3/S)/CS reaction is Penning ionization.
