Self-consistent relativistic molecular calculations of superheavy molecules: (_110 X)F_6
(1978)
Using new relativistic molecular calculations within the Dirac-Slater scheme it is now
feasible to study theoretically molecules containing superheavy elements. This opens a
new era for the prediction of the physics and chemistry of superheavy elements. As an
example we present the results for (_110 X) F_6, where it is shown that relativistic effects are nearly of the same order of magnitude as the crystal-field splitting.

Kinematic dipole model for the anisotropy of quasimolecular X-rays
(1978)
For the angular dependence of quasimolecular X-ray emission in heavy ion colliding systems we present a semiclassical adiabatic model taking into account spontaneous dipole radiation. Using the most characteristic levels from a DFS-correlation diagram we are able to explain the behaviour of the observed anisotropy.

Threshold behaviour of L x-ray excitation in Xe - Ag collisions
(1978)
In the collision system Xe - Ag, the thresholds for excitation of quasimolecular L radiation and characteristic Ag L radiation have been found to lie at about 5 MeV and 1 MeV, respectively. These results are discussed on the basis of ab initio calculations of the screened interaction potential and the electron-correlation diagram.

An ab-initio calculation of the Coulomb explosion of N_2 after heavy-ion bombardement
(1978)
Self-consistent-field calculations for the total potential energy of highly ionized N_2 molecules are presented. We compare these calculations to the experimentally observed energy released in the Coulomb explosion of ionized N_2 molecules created after collision with fast heavy ions. The most important electronic states of the fragment ions are determined.

Retardation effects in ion-ion collisons [collisions]
(1978)
The modification of the two center screened electronic Coulomb potential due to relativistic kinematical effects is investigated in the Coulomb gauge. Both nuclear and electronic charges were approximated by Gaussian distributions. For ion velocities v/c =0.1 the effect may roughly be approximated by a 0.1% increase in the effective strength for the monopole term of the two center potential. Thus for ion kinetic energies not exceeding a few MeV/nucleon this relativistic contribution induces small effects on the binding ...
