[en] The facilities at the Studsvik Research Centre serve as a basis for fundamental research. The neutron diffraction work aiming at determining crystal structures has continued both with single crystals and powders in collaboration with university groups from Lund, Stockholm, Goeteborg and Uppsala. Results are reported for a number of compounds. The neutron scattering studies deal with liquid metals and elementary excitations in liquid ³He. Another project is to equip a reactor channel with a Sc filter to produce nearly mehoenergetic neutron beams. The R2-0 reactor is used in the isotope-separator-on-line experiment OSIRIS. The main research activity has been connected to studies of the properties of short-lived neutron-rich isotopes of zinc, gallium, germanium, bromine, cadmium, indium and iodine. Thermal neutron induced fission of ²³⁵U at OSIRIS and heavy-ion induced regetions are studied as a collaboration project with a group at Lawrence Barkeley Laboratory. The Van de Graaff-accelerator is used for experiments in elastic scattering from radiogenic Pb and ²⁰⁹Bi, inelastic scattering from ⁸⁰ Y and ¹⁴¹Pr. The accelerator is also used for analytical determinations using the PIXE technique. The radiation chemistry group has continued the studies of primary reactions in crystalline organic materials using pulse radiolysis and ESR spectroscopy techniques. The kinetics of the decay of the ions is determined after irradiations with a pulsed 800 kV electron accelerator of type Febetron. The laboratory has been financially supported by the Natural Science Research Council and the Board of Technical Development. A description of research programs is given and list of publication is presented. (G.B.)
