The radiation emitted by the radiative charge transfer He/sup +/+Ne..-->..He+Ne /sup +/+h..nu.. has been observed with the use of a selected-ion drift apparatus in conjunction with spectroscopic instrumentation. The two observed emission features with wavelengths around 4100 and 4240 A evidently arise from transitions in the short-lived HeNe/sup +/ excited molecular ion which is formed in the collision. Mass-spectrometric observations of the product ions indicated that the reaction occurred with a rate coefficient of 1 +- 0.3 x 10/sup -15/ cm/sup 3//sec at a gas temperature of 300 K. In addition to charge transfer, a second associative reaction channel producing HeNe/sup +/ ions is found to have an effective rate coefficient of about 2 x 10/sup -16/ cm/sup 3//sec.
