The differential cross section for Ar(e+, Ps e−)Ar++ was measured for the first time. The outgoing Ps atom was detected in time correlation with the Ar++ ion to identify this particular cross section. At an emission angle of 45°, a distinct dip in this transfer ionization, the formation of Ps combined with the ejection of an electron, was observed. The width of this structure is not wider than our effective angular acceptance of ±2.5°. No such feature is observed in the transfer reaction, usually referred to as Ps formation. Thomas scattering is suggested as a possible cause for this phenomenon.

It is pointed out that the y-dependence of the differential cross-section for various types of neutrinos on the electron promises to be a sensitive testing ground of the electroweak Standard Model at KAON in Vancouver. Estimates of the flux requirements are given and the feasibility of such experiments is discussed.
