Query: Intense Infrared Scintillation of Liquid Ar-Xe Mixtures   Intense infrared (IR) light emission from liquid Ar-Xe mixtures has been
observed using 12 keV electron-beam excitation. The emission peaks at a
wavelength of 1.18 $\mu$m and the half-width of the emission band is 0.1
$\mu$m. Maximum intensity has been found for a 10 ppm xenon admixture in liquid
argon. The conversion efficiency of electron beam-power to IR-light is about 1%
(10000 photons per MeV electron energy deposited). A possible application of
this intense IR emission for a new particle discrimination concept in liquid
noble gas detectors is discussed. No light emission was found for perfectly
purified liquid argon in the wavelength range from 0.5 to 3.5 $\mu$m on the
current level of sensitivity.
