The expert systems for analysis of electron energy-loss spectra

In this paper is presented development of the expert systems for threshold spectra analysis, starting from firstly developed expert system for atom threshold spectra analysis, up to the expert system for analysis more complex molecule threshold spectra (firstly two-atomic and then tree-atomic molecules). The goal of the expert systems application is to automate, speed up and improve process of spectra analysis. Interest for threshold spectra originates from the fact that, by studding them, it is possible obtained information about processes which happened on energies near reaction threshold. Also, in these spectra can be seen peaks that correspond to forbidden transitions and which can't be seen in the optical spectroscopy. For testing of the expert systems, we used the threshold spectra for the He atom, and N-2 and SO2 molecules. All these spectra are obtained on threshold spectrometer in Institute of Physics in Zemun (Laboratory for Atomic Collision Processes).
