Abstract

Interest in near-threshold ionization is discussed and an experiment is described aimed at its measurement by positron impact. The method involves an ion time-of-flight system triggered by the detection of the scattered projectiles. This latter task will be assisted by a weak electric field penetrating the interaction region.
