Abstract

A new vacuum ultraviolet-light source is described which emits a strong continuous emission spectrum from 1500A to 2250A. This source is constructed of Pyrex, is charged with xenon, and carries a fluorite window which allows the tube to be completely sealed off from the vacuum system. Microwave energy at a frequency of 2450 mc/sec is used to excite the emission. Molecular xenon is presumably responsible for the continuum and the main transition is probably ³∑_u⁺→¹∑_g⁺ with some contribution from ¹∑_u⁺→¹∑_g⁺. The source has been used to photograph the Schumann-Runge absorption bands of oxygen in the first order of a 21-foot vacuum grating spectrograph.
