The current transients of prebreakdown electron avalanches in uniform electric fields in oxygen are studied with a bakable drift tube and a time resolution of about 1% of the ion transit time involved. At this low time resolution, electronic-current

Measurements of Townsend's first ionization coefficient α in oxygen are reported. Account is made of the various reactions of the negative ions involved (O - , O - 2 , O - 3 ). The resulting α-values are smaller than those obtained previously.
