Abstract
The scintillation and ionization yields in liquid argon by α particles and fission fragments have been measured as a function of the applied electric field (≤38 kV/cm). The quenching due to high excitation density does not depend on the field for ≳4 kV/cm for α particles. The scintillation due to α particles shows a maximum at about 1.5 kV/cm. This increase (2.5±0.7%) of the scintillation at low fields has not been observed heretofore and is ascribed to the presence of a quenching process at zero field.Keywords
