Abstract:
The object of investigation is the optical characteristics of Br$_{2^-}$, Cl$_{2^-}$, XeBr, and XeCl excilamps excited by microwave radiation. The power of the microwave discharge is determined from a pressure jump in the bulb of the lamp. Conditions for the effective generation of XeCl$^*$ and XeBr$^*$ exciplexes in cylindrical lamps are found. The efficiency of generation of these exciplexes equals 7.2 and 7.8%, respectively.
