Abstract

Triple differential cross sections are calculated for the ionization of NH₃ by positron impact in coplanar and perpendicular geometrical arrangements. The cross sections are determined for symmetrically emerging particles with equal energies. The positron cross sections are compared with previously calculated electron cross sections for the same kinematical conditions.
