Abstract
A spectroscopic study of liquid argon from the vacuum ultraviolet at 110nm to 1000nm is presented. Excitation was performed using continuous and pulsed 12 keV electron beams. The emission is dominated by the analogue of the so-called 2nd excimer continuum. Various additional emission features were found. The time structure of the light emission has been measured for a set of well-defined wavelength positions. The results help to interpret literature data in the context of liquid rare-gas detectors in which the wavelength information is lost due to the use of wavelength shifters.
