Emission spectrum and quenching kinetics of Xe2F*

Abstract
Experiments demonstrating the existence of the triatomic rare‐gas excimer Xe2F* are reported. Three‐body quenching of XeF*(B,C) yields Xe2F*, which radiates around 610 nm with a bandwidth full width at half‐maximum (FWHM) of 120 nm. The two‐body quenching constants of Xe2F* by NF3, Xe, and Ar as well as the radiative lifetime of 152 ns are determined.
