Abstract : The report gives the status of three experiments: (1) Low energy ion reactions. In this experiment we measure angle and energy distributions of products from ion molecule reactions, with mass spectrometer selected primary ion beams. A notable development is a particularly simple energy analyzer with high transmission and good resolution. (2) Low energy elastic scattering. This experiment is designed to operate below one eV energy and uses a unique system of masks with ring-shaped openings to define the scattering angle. (3) Penning effect. This experiment is intended to study the energy released as translational energy in Penning effect collisions, notably He(*) + O - O(+) + He + e. (Author)
