Presented research achievements connect atomic and molecular phenomena with studies of surfaces and materials, and at the same time open possibilities for further interdisciplinary investigations and development. The research filed of the program group are directed towards understanding of multiparticle processes in atoms, study of ionization mechanisms with ions, corrosion phenomena on the material surfaces and interpretation of ultrathin layers on the surfaces. Important part of the program is oriented to development of new spectrometric methods and experimental tools, application of possibilities at new J.Stefan Institute (JSI) tandem accelerator, as well as to the development of control systems for new generation synchrotron light sources. In more details the results are as follows: - Electron spectrometry has been implemented with spectrometer for slow ions, based on time-of-flight (TOF) measurements. In the filed of theoretical atomic physics the calculation of double differential cross sections for nonelastic electron scattering in the vicinity of the Ne 1s threshold has been developed. The branching ratios between the autoionization and fluorescence decay of 2s(-1)np(1)1P states in neon for n:10-13 have been extracted and the results compared with the Gas Phase experiment at Elettra synchrotron. - High resolution X-ray spectrometry has became equipped with a new spectrometer. It is still open question of optimal X-ray detection, but at the moment the imaging plates (IP) are being applied for this purpose. In collaboration with University of Fribourg the measurements of satellite and hipersatellite transitions have been done at the PSI in Villingen. - Ionization cross-section at symmetric and nearly symmetric ion-ion collisions, as measured at Lund University, have been completed with theoretical calculations using statistical model. - With high resolution absorption spectrometry two extensive measuring cycles in Hamburg and Orsay have been realized in collaboration with Hasylab and LURE groups. Besides atomic absorption measurements for collective excitation studies in atoms (Xe, Cs) a comprehensive structure analysis of new materials by EXAFS method was performed. The whole complex of measurements related to the multielectron excitations at elements from Ge to Rb has been evaluated. - At introducing new experimental techniques related to surface physics studies a method for angle resolved detection of photoelectron diffraction, as based on variable polarization of the incident light, has been developed and tested. The measurements at the ALOISA beamline showed, that the information offered by spectra measured with different polarization of incident light can be distinguished. When studying ultrathin layers of Fe it has been observed that structure formed substantially differs from the one of 3D Fe crystal with the body-centered –bcc cube. Structural characteristics of thin Fe layers open new possibilities for various magnetic properties of quasi-two-dimensional films. The deposition of 1/3 Sn layer on Ge(111) substrate has been studied in details. - The characteristics of multilayer Ti/TiN films have been studied for the case of aggressive environment simulated by humid salt atmosphere. Here, various methods from Mössbauer conversion electron spectrometry to raster electron microscopy have been applied. A new method for fast electrochemical determination of thin film porosity has been implemented. The research of magnetic thermo-desorbed LB films has been continued also by using Mössbauer conversion electron spectrometry. - An important part of the program has been collaboration for the construction of ANKA synchrotron light source in Karlsruhe. Within the project, a control system for commissioning and operation of the accelerator has been developed. - At the electrostatic tandem accelerator installed at J.Stefan Institute, recently, the development and use of ion beam analytical (IBA) methods have been...
