Abstract

The laser optogalvanic (LOG) spectrum of cesium vapor at —50 m Torr in a low power (Si W), —30 MHz radiofrequency discharge has been recorded in the range 16,250 to 16,860 cm-1. Members of several Rydberg series (6p -► ns, 6p -» nd, 5d -* np and 5d -► nf) that terminate on the first ionization limit have been observed. The line broadening of high-n (ns30) f- levels in cesium is considerably less than in xenon. The excessive broadening in xenon is attributed in part to interactions of the Rydberg electron with the open- shell core.
