Notes:
The photoabsorption spectrum of the Kr+2 ground electronic state (X 2Σ+u) has been measured in the ultraviolet (257–355 nm) by a fluorescence suppression technique. Peak absorption is recorded at ∼330 nm and the spectral width of the observed continuum is ∼60 nm (FWHM) which is ∼25% smaller than the value predicted by theory for a Kr+2(X) vibrational distribution thermalized at 300 K. Similar experiments with Ar/Kr mixtures: (1) reveal weak absorption attributed to ArKr+ peaking at ∼280 nm, and (2) suggest that the ArKr+ ion is rapidly converted to Kr+2 by a displacement reaction. © 1995 American Institute of Physics.
