“…28 -3o More recently, Webster and Rostas 31 observed in emission KXe molecular bands associated with the 3 2 D and 5 2 P states of K and an excitation spectrum of the molecule [obtained by scanning a blue dye laser while monitoring the resonance K(4 2P 3 / 2 --+ 4 2S I / 2 ) transition at 766.5 nm] revealed these same new bands between 400 and 500 nm. Shahdin et al 32 and Schilowitz and Wiesenfeld 33 have also shown that ArF (193 nm) or KrF (248 nm) laser photodissociation of alkali-halide salts in a rare gas background is capable of producing weak NaXe,32 CsXe,32 or KXe 33 fluorescence.…”

The ultraviolet and visible absorption spectra of potassium vapor-xenon mixtures have been studied for [K] and [Xe] as large as 7X 10 17 and 4X 10 19 cm-3 , respectively. Collision-induced absorption is observed in the ultraviolet (285 ~A S 370 nm) for the 4s -nJ, nd (4 ~ n ~ 8) transitions but peak absorption lies an average of -0.6 nm to the red side ofthe position of the electric dipole forbidden line. The 4s -4/, 5Jtransitions, in particular, are quite strong, having peak reduced absorption coefficients measured to be 1.1 X 10-39 and 2.6 X 10-40 cm s , respectively. Also, the KXe (e 2.2") exciIher has been observed in absorption for the first time. Absorption at the band peak (reduced absorption coefficient of -2X 10-40 cm s at A = 507 nm) is roughly two orders of magnitude weaker than that for the analogous bands of CsXe and RbXe and is displaced at least 5 nm to the blue side of the peak ( -520 nm) in the emission spectrum. Six reproducible undulations to the blue side of the absorption maximum display a periodicity of 111 ± 17 cm -I.
