Senior staff
Ph D students
After some reshuffling of tasks former colleagues have other positions. Ton Raassen is now working at the
Astronomical Institute "Anton Pannekoek" and
Space Research Organization of the Netherlands (SRON) on X-ray spectra of
CHANDRA and XMM and Peter Uylings is participating in
the AMSTEL Institute on the innovation, research and development
of mathematics and science education.
Research programs
The Atomic Physics Theory Group deals with a variety of phenomena in atoms such as inner shell excitation,
electron capture, hollow atoms and analysis of atomic spectra. Computational methods used to make ab initio
calculations of atomic structures are Multi Configuration Hartree Fock and Multi Configuration Dirac Fock.
Other methods applied are B-splines and the recently developed Orthogonal Operator Technique.
Data from the orthogonal operator technique (energy level values and transition
probabilities) are available in our database (anonymous ftp) at ftp://ftp.wins.uva.nl/pub/orth or by clicking on the item above.
