In this work, we confirm this prediction: for the first time, visible-range EL has been observed in liquid Ar at electric fields reaching 90~kV/cm, using Gas Electron Multiplier (GEM) and Thick GEM (THGEM) structures. Absolute light yields of the EL were measured and found to be in excellent agreement with the theory, provided that momentum-transfer cross section of electron-atom scattering (instead of energy-transfer one) is used for calculation of NBrS cross section.",
