Abstract
A model of the ionization pathlength PDF is reformulated with new parameters that have more physical significance and allow further investigation. The transition from the dead space effect to the dead space plus resonance effect is investigated and a new measure, the overshoot factor, is suggested as the method for indicating the degree of resonant behaviour. The nonβlocal model is extended for nonβuniform electric field profiles. When this extended model is fitted to Monte Carlo data derived for four different electric field profiles, a fairly consistent set of parameters is found. (Β© 2009 WILEYβVCH Verlag GmbH & Co.
