A scintillation response and an ionization yield in pure xenon and mixtures of it with methane

Abstract

The scintillation response to an α source ( 241 Am) and the ionization yield in pure gaseous xenon and its mixtures with 0.2–2% of methane were measured at a pressure of 26 atm and different values of reduced electric field E/N . Both light and ionization yields in xenon were shown to decrease with increasing percentage of methane.
