Introduction
Collisions between electrons and atomic particles (atoms and
molecules) in both ground and excited states have been of broad
interest in science and application. Processes like elastic
scattering, excitation, ionization and autoionization,
dissociative attachment, and others are studied. Research
activities within the Laboratory for atomic collision processes
are aimed at quantifying and understanding the fundamental basis
for these processes. There are six main research areas currently
in progress: ESMA, UGRA, SELE, TR-LIF, SPEPRA and OHRHA. Some of these
areas have openings for postgraduate research projects and
descriptions of these can be found under Postgraduate Research
Projects. Much experiance has been accumulated in the design of
electron spectrometers, formation of electron beams, particle
detection, as well as in high vacuum technology. Special
attention is paid on signal processing techniques.

NATIONAL RESEARCH PROJECTS
"Electron and laser spectrometry and collisional cross sections for atoms, ions, molecules, metastables and biomolecules"
Publications: 2006 , 2007 , 2008 , 2009 , 2010
"Experimental investigation of laser and electron interaction with atoms, metal vapours and molecules"

Current areas of research activities are:
(1) ESMA - Electron Spectrometer for Metal Atoms - is
a high resolution hemispherical electron spectrometer designed
for the study of differential cross sections of elastic and
inelastic scattering of intermediate energy electrons (10-100 eV)
by metal atoms.
(2) UGRA - Electron Spectrometer for Angular Distributions -
is an electron spectrometer with high current electron beam gun and
double mirror cylindrical analyser designed for measuring angular
distribution of ionic fragments from molecular dissociation upon
electron impact.
(3) SELE - Stepwise Electron Laser Excitation - is an
apparatus, currently in preparation status, which is designed for
simultaneous excitation of atoms by electron beam and laser beam
in order to investigate processes of electron excitation of
fine-structure levels as well as the excitation of excited atoms.
It utilizes an cylindrical throchoidal monocromator as a source
of monoenergetic electrons.
(4) SPEPRA - Threshold Electron Spectrometer - is an high
resolution electron spectrometer for collecting threshold
excitation spectra of atoms and/or molecules.
(5) TR-LIF Time Resolved Laser Induced Fluorescence
(6) OHRHA Omicron High Resolution Hemispherical Analizer
Postgraduate Research Projects:
(1) Measuring of autionization spectra utilizing electron spectrometers.
(2) Implementation of Logical model of Information system in
Atomic Collision Physics. Formation of Data base for
electron-atom scattering processes and cross sections.
(3) Design of resistively heated oven for producing molecular beam of biomolecules.
