Both the probability that such transfers occur and the mechanism by which the transfer takes place, vary with the gas composition and pressure. With a view to developing a microscopic electron transport model that takes Penning transfers into account, we use this dependence to identify the transfer mechanisms at play. We do this for a number of argon-based gas mixtures, using gain curves from the literature.eninfo:eu-repo/semantics/openAccessGaseous detectorsIonization and excitation processesCharge transport and multiplication in gasDetector modelling and simulations II (electric fields, charge transport, multiplication and induction, pulse formation, electron emission, etc)Filled proportional-countersCross-sectionsOscillator-strengthsRadiative lifetimesExcited-statesAr-ITransition-probabilitiesMolecular-structureEnergy resolutionKinetic-analysisInstruments & instrumentationElectric fieldsGas mixturesMixturesElectron transportExcitation processGain curveGas compositionsGas gainModelling and simulationsTransfer mechanismsIonization of gasesArticle0002805261000072-s2.0-779523704511305Instruments & instrumentationProportional Counters; Avalanches; Parallel Plates
