Measurements of ionization and attachment coefficients in chlorine

摘要: Ionization and attachment coefficients, α η, have been obtained by observing, in pure chlorine at pressures of from 1 to 10 torr, the variation prebreakdown ionization currents with distance between parallel electrodes reduced fields range 70-150 v cm-1 torr-1. Values - η for values E/p up 250 The coefficient α/p rises 022 = 70 20 150, while η/p falls 084 approximately 025 same range. No pressure dependence could be found. These are much larger than those indicated an extrapolation results Bailey Healey.
