Energy loss of charged particles in a gas has been estimated by a computer simulation technique with a view of studying primary cluster counting as a mean of the particle identification. Primary electron yield and secondary multiplication have been estimated through a detailed calculation of the atomic processes. Results are presented for pure argon in terms of cluster size distributions and relativistic rise of the number of clusters: the latter reaches a plateau at a 3' of 200 and of level of 1.32 times minimum ionization. Limitations to detector resolution due to electronic dead time and longitudinal diffusion of the electrons drifting in the gas are presented. Such limitations are introduced in a comparison between the performance in particle separation of detectors based on energy loss, making use of pulse height measurement or cluster counting.

“…This study describes DDCS measurements and theoretical First Born Approximation (FBA), corrected by Gamow factor, for methane ionization dynamics at impact with a 250 eV electron for the rst time in the literature. The earlier pioneering DDCS studies for methane molecule have been reported under kinematics for 500 and 1000 eV electron impact by Opal [5] and Oda [6], respectively. DDCS measurements of electronmethane interactions have been also measured at intermediate energies [78].…”

In this study, experimental and theoretical double dierential cross section (DDCS) data for methane-electron interaction mechanism after the impact of a 250 eV electron have been comprehensively determined for a wide energy range of the detected electron, from 50 to 225 eV. The rst Born-One Coulomb wave modeling with Gamow factor has been calculated to analyze experimental DDCS results for a correct description of the electron impact ionization of methane molecule. It is found that these theoretical calculations are successful to describe the postcollision interaction eects due to the Coulomb long-range interaction between the outgoing electrons in the nal state. A considerable agreement is found between experimental and theoretical results.
