• decay properties of nuclei near the double shell closure 100Sn,• study of the Gamow-Teller resonance in beta decay of nuclei below 100Sn, • investigation of the rare decay mode of exotic nuclei close to • the proton drip line: delayed proton and alphas, protons and two protons from the ground state, cluster emission,• study of the properties of N ≈ Z nuclei• search for microsecond isomers• mass measurements

Investigation of hot and compressed matter, in particular strangeness production in nucleus-nucleus collisionFlow intensity in HI collisions


In-medium modyfications of kaons and antikaons The properties of kaons and antikaons are modified in dense baryonic matter. In mean-field calculations, this effect is caused by repulsive K+N potential and attractive K-N potential. K- yield enhancement is explained by strangeness exchangereactions, and reduction of K- effective mass in dense nuclear matter

AND


High-resolution dilepton spectroscopy

First invariant mass spectra from C-Ccollisions


ATOMIC PHYSICSATOMIC PHYSICS

1. Resonant transfer and excitation studies in heavy-ion atom collisions.2. Radiative electron capture – time reversal of photoionization.3. Multiple electron processes in heavy-ion atom collisions.4. Stringent tests of QED in strong fields – Lamb-shift measurements.
