The Townsend first ionization coefficient α, electron attachment coefficient η and effective ionization coefficient α^^- (=α-η) in SF_6 and xenon gas mixtures were measured by the steady-state Townsend method for 22.6 &les; E/p &les; 94 V・mm^<-1>kPa^<-1> and mixture ratios of 10:90, 25:75, 50:50, 75:25 and 90:10. The limiting E/p in SF_6-Xe, (E/p)_<lim>, which represents E/p for α/P=n/P, was derived from the pre-breakdown current growth measurements, which varies approximately linearly with SF_6 concentration in the SF_6-Xe gas mixtures.
