Abstract :
An increase in scintillation of up to 17% has been observed in liquid argon with the application of low electric fields (<6 kV/cm) for 1H, 4He, 18O and 36Ar ions of energy 1-35 MeV/u. This increase occurs at a field much lower than that required for the proportional region (106 V/cm). The observed phenomenon is attributed to the recovery of quenching in the high excitation density region of the particle track by the external field
