The primary ionization coefficient for the Ar-CH4 mixtures remains within 30% of that for pure argon but an optimum concentration of 0.13% of propane in the Ar-C3H8 mixture gives ri to a Penning effect almost comparable in intensity to that obrved by Kruithof and Penning (1937) 花非花歌曲
待人之礼in Ne-Ar mixtures; thus at E/p0=5 v cm1 torr1 at 0°c, the coefficient is incread by a factor of 200 above that for pure argon. Becau of the quenching property of hydrocarbons, it is shown that it is possible to reduce the condary ionization coefficient of argon as much as 107 times; at low and high E/p0 the effectiveness
