Abstract
D/μ values (diffusion coefficient/mobility), drift velocities and attachment coefficients of electrons in oxygen have been measured over the range 5<E/p25, the measurements have also yielded values of Townsend's primary ionization coefficient. If electron detachment is neglected, the D/μ values and drift velocities are in good agreement with the available data, while the attachment coefficients differ substantially from some of the reported values. The overall accuracy of the D/μ values and the drift velocities is estimated to be better than ±3%, while the accuracy of the attachment coefficients obtained varies from ±3% for E/pE/p values.
