The main research activities of the Department for Low and Medium Energy Physics are oriented towards the following fields :

low energy or atomic physics

medium energy physics,

development of metrology-based nuclear measuring techniques and instrumentation.

In the field of low-energy physics, main consideration is given to basic research in atomic physics, which take place at home facilities and in international centres. Special attention is paid to collaboration with the international research community, and good relations have been established with Johannes Kepler University, (Linz, Austria), Hasylab, DESY (Hamburg, Germany), LURE (Orsay, France), NSLS (Brookhaven, USA), Sincrotrone Trieste (Trieste, Italy), Forschungszentrum Karlsruhe (Karlsruhe, Germany), University of Mainz (Mainz, Germany), Lorand Ötvös University (Budapest, Hungary), University of Madrid (Spain), University New South Wales (Canberra, Australia), University of Göttingen (Germany), Max-Planck Institut für Metallforschung (Stuttgart, Germany), ATOMKI (Debrecen, Hungary), University of Fribourg (Swiss), University of Rome (Italy) and National University of Singapore (Singapore). One of the main future prospects of the Department is the planning and construction of the Slovenian beam line BOSS at the synchrotron light source ELETTRA near Trieste, which will offer excellent research possibilities for the scientific community in Slovenia in general. Applied research in the field is devoted to the development and implementation of nuclear spectroscopic methods such as X-ray fluorescence spectrometry, accelerator based spectrometries, and Mössbauer spectrometry in various interdisciplinary studies. With the aim of improving analytical capabilities of these techniques, an upgrade of the existing electrostatic accelerator at the J.Stefan Institute, Ljubljana, is planned, which will form a basis for developing a Laboratory of Nuclear Spectrometries.

Within the field of medium-energy physics, the study of interplay of nucleon and sub-nucleon degrees of freedom and research of highly excited nuclear states with advanced experimental and theoretical methods belong to most promising field in nuclear physics. This kind of research is no longer possible without international collaboration. Thus we are members of the A1 Collaboration at MAMI, University of Mainz, and members of the user group at TJNAF, USA. We are also working on the CELSIUS storage ring (Uppsala, Sweden), collaborating with KFA Jülich (Germany) and the Slovak Academy of Science (Bratislava, Slovak Republic).

The field of metrology-based nuclear techniques and instrumentation has to be one of the main prerequisite in each country which wishes to transfer and use the results of basic research in physics in other fields like ecology, safety, medicine, and industry. This should be essential prerogative of any nation. Particular attention is paid to the development of Secondary Standard Dosimetry Laboratory and to radioactivity monitoring in Slovenia.
