Probability of such additional ionizations can be calculated from the measured gas gain fits. In the present work, Penning ionization processes for Ne-CO2 and Ne-N-2 mixtures have been investigated with a newly developed model. The decreases in the transfer rates observed at high molecular gas concentrations indicate the existence of a remarkably interesting transfer mechanism for the excited neon atoms.eninfo:eu-repo/semantics/closedAccessIonizationGasesGaseous 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)Science & technologyTechnologyInstruments & instrumentationArticle00063678610001416310.1088/1748-0221/16/03/P03026
