Abstract
Fano factors in liquid argon, krypton, xenon and xenon-doped liquid argon are estimated from the Fano formula by using the parameters in the energy balance equation for the absorbed energy of ionizing radiation. As a result, it is shown that the values for liquid argon, krypton and xenon are smaller than those in the gas phase and the value for xenon-doped liquid argon is smaller than that for liquid argon as in argon-molecular gas mixture. In particular, the value for liquid xenon is extremely small, i.e. about 0.05, which is comparable to that for Ge(Li) detectors. Using the so obtained Fano factor and an electronic noise level which can easily be achieved, the fwhm in the liquid xenon ionization chamber is estimated to be about 3 keV for 1 MeV electrons.
