Electron–ion recombination in radiation tracks in liquid argon: a computer simulation study

Article

Abstract

A simulation method is proposed to model electron–ion recombination in radiation tracks in liquid argon at 87 K. The method is applied to calculate the electron escape probability in clusters of up to 20 pairs of electrons and cations that represent a fragment of the track. The results reproduce the basic features of the track recombination in liquid argon observed in experiment.
