16. S2n (11Li) = 0.3 MeV 3/2-: Er=0.43(2) MeV, G=0.15(8) MeV (gs) 1/2-: Er=1.0(1) MeV, G=0.75(8) MeV Halo Nuclei Continuum spectroscopy Reinhard Kulessa

17. Reinhard Kulessa

18. Investigation of hot and compressed matter, in particular strangeness production in nucleus-nucleus collision Flow intensity in HI collisions Reinhard Kulessa

19. 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 exchange reactions, and reduction of K- effective mass in dense nuclear matter AND Reinhard Kulessa
