Energy distributions of scattered positrons (e+) and ejected electrons (e-) resulting from 100 eV e+-Ar collisions have been determined at 30-degrees and 45-degrees in coincidence with the remnant Ar+ ions. A calibration method has been employed to convert the measured intensities into absolute cross sections, The experimental data are compared with values calculated by a classical-trajectory Monte Carlo method. The agreement is good for the secondary e- but poor for the scattered el. The ratios of the measured secondary e- intensities at 15 eV have been determined for e- and e+ impact and compared with existing experimental and theoretical values.
