Interpretation of quasimolecular L X-rays in heavy-ion collisions
(1977)
Using a relativistic selfconsistent correlation diagram a first interpretation of the shape and position of L MO X-rays is given within a quasi-adiabatic model.

Relativistic many-electron SCF correlation diagram for superheavy quasimolecules: Pb - Pb
(1981)
We present the first relativistic many-electron SCF correlation diagram for a superheavy quasimolecule: Pb - Pb. The discussion shows a large number of quantitative as well as qualitative differences as compared with the known one-electron correlation diagram.
Aufsatz
Kr - Kr correlation diagram and its use in heavy-ion collisions
(1981)
A realistic self-consistent charge correlation diagram calculation of the Kr{^2+} - Kr{^2+} system has been performed. We get excellent agreement for the 4(3/2)_u level with an experimentally observed MO level at large distances. Possible reasons for discrepancies
between experiment and theory at small distances are discussed.

Values for the electron screening in muonic atoms for all Z
(1975)
The electron screening correction in the X-ray transitions in muonic atoms is calculated within a relativistic SCF Hartree-Fock procedure for many transitions and all Z.

Inclusive probabilities for the scattering system 16 MeV-S{^16+} on Ar
(1991)
We performed ab initio calculations of many particle inclusive probabilities for the scattering system 16 MeV-S{^16+} on Ar. The solution of the time-dependent DIRAC-FOCK-SLATER-equation is achieved via a set of coupled-channel equations with energy eigenvalues and matrix elements which are given by static SCF molecular many
electron calculations.

{2p_\pi}-{2p_\sigma} crossing in heavy symmetric ion-atom collisions: I. Level structure
(1982)
Ab initio self-consistent DFS calculations are performed for five different symmetric
atomic systems from Ar-Ar to Pb-Pb. The level structure for the {2p_\pi}-{2p_\sigma} crossing as function of the united atomic charge Z_u is studied and interpreted. Manybody effects, spin-orbit splitting, direct relativistic effects as well as indirect relativistic effects are differently important for different Z_u. For the I-I system a comparison with other calculations is given.

On the chemistry of superheavy elements around Z = 164
(1969)
With a relativistic Hartree-Fock-Slater calculation we determined the most stable configurations of the
elements of the possibly quasistable island around Z = 164. It is found that the expected noble gas at Z = 168 should not occur, but instead the element Z = 164 should have the properties of a noble gas.
