> ''' Our researchers perform a basic and applied research in the low and medium energy physics. The first is relates to the work in the atomic physics while the second contributes to the knowledge of the nuclear physics. We deal with radiological environmental protection mainly concerned with the monitoring of environment in the vicinity of nuclear power plant and with the monitoring of the radioactivity in the food. A mobile ecological laboratory is a part of our Department, besides the other three laboratories:<

>In atomic physics we perform experiments to test new model approaches, while the phaenomena, which are already fairly well understood are used to set-up and run the analitical methods. The basic research in this area is focused onto the high resolution fluorescence measurements from atomic targets, simple molecules and solids which are performed in the energy and time domain and possibly also in the external nonzero field environment. We do Auger electron-ion coincidence measurements. A near edge structures of different targets with short range order are measured by means of photoabsorption (XANES, EXAFS) and high resolution resonant x-ray Raman processes. Recently a structure of cisplatin was studied, which is an important substance in the cancer chemotherapy. We are regularly engaged in measurements at many European synchrotrons (Elettra, Bessy2, ESRF, Desy). <

> An ion beam accelerator Tandetron with 2-MV maximum terminal voltage operates at the Microanalytical Center [[http://www.rcp.ijs.si/~mic/|MIC]] which is in the frame of the department and provides the ion beam current for several analytical methods: PIXE, ERDA, NRA. These methods are used to determine the average elemental concentrations in the bulk as well as the to do the depth profiling and lateral mapping on the um scale with our ion microbeam. Recently, our x-ray detectors were equipped with the polycapillary to set-up for the first time the 3D-PIXE technique. We study aerosol samples, degradation of historical ink manuscripts and do the micromachining with the proton microbeam. M=F6ssbauer spectroscopy is used to study the iron compounds. <
