Electronic configuration in the ground state of atomic lawrencium
(1974)
Self-consistent relativistic Dirac-Hartree-Fock calculations have been made of some lowlying electronic energies for the atoms of all elements in ground-state ds^2 electron configurations.
The results indicate that, contrary to some previous estimates, the ground electronic
state of atomic Lr could be in either the 5f^14 6d7s^2 or the 5f^14 7p 7s^2 electron configuration.
The separation between the lowest energy level of the 5f^14 6d7s^2 configuration and the lowest energy level of the 5f^14 7p7s^2 configuration ...

Zur Vakuumpolarisation in Myonenatomen
(1969)
The various approximations of vacuum polarization potential and the higher order
corrections up to \alpha^3 are reviewed and quantitatively dicussed. The quadrupol part of the vacuum polarization is established. It leads rather straight forward to a small
contribution of vacuum polarization to nuclear polarization. These effects are quantitatively investigated.

Beam-foil-excited auger transitions in neon
(1975)
Energy spectra of electrons ejected from collisions between a carbon foil and Ne
projectiles with energies between 1.4 and 20 MeV have been measured. Continuous and
discrete electron energy distributions are observed. Auger transitions of foil-excited Ne have been studied. Using relativistic Dirac-Fock multiconfiguration calculations, most of the measured Auger transitions have been identified.

Electronic structure of UF_5
(1979)
Non-relativistic and relativistic self-consistent Hartree- Fock-Slater and Dirac-Slater models have been used to calculate one-electron energy levels and ionization energies for UF_5. The calculations were performed in an assumed structure of C_4v symmetry with the uranium atom at the center of mass of the molecule. The spacing and level ordering are compared
with earlier results obtained with the MS X\alpha method using the muffin-tin approximation. Connections with the multiphoton isotope separation scheme of UF_6 ...

The problem of noncharacteristic quasimolecular X-rays in heavy ion collision
(1976)
Quasi-molecular X-rays observed in heavy ion collisions are interpreted within a relativistic calculation of correlation diagrams using the Dirac-Slater model. A semiquantitative description of noncharacteristic M X rays is given for the system Au-I.
