The appearance of a large mass 12 peak in pure helium afterglows prompted further investigations, from which it is believed that the maas 12 peak is carbon from a CO impurity, probably a result of outgassing of the walls of the discharge chamber, Mixtures of oxygen with helium and neon have been examined in an attempt to measure the O/sup +/ to O/sub 2/ charge transfer rate. Afterglows in hydrogen, water vapor, and nitrogen-- hydrogen mixtures have also been studied. (auth)
