Observation of New Satellites in the Cs-Ar System Using Resonance Ionization Spectroscopy

Abstract

The absorption line shape of Cs-Ar system is recorded using two-photon ionization of the system with $\mathrm{Cs}\mathrm{}\left(7P\right)\mathrm{}$ as an intermediate state. New satellite structures in the wings of $\mathrm{Cs}\mathrm{}\left(7P\right)\mathrm{}$ are observed which were not resolved in previous absorption measurements. Also the absolute absorption cross section in the blue wing is measured.
