Visible Emission Bands ofKXenPolyatomic Exciplexes

Abstract
Intense green emission bands are observed when potassium vapor in several amagats of xenon is illuminated with the 4067-Å line of a krypton-ion laser. The very pronounced dependence of this green band on temperature and xenon density is consistent with the behavior expected for KXen exciplexes with n ranging from 1 to at least 4.
