Konstruktion oder Rekonstruktion? Überlegungen zum Gegenstand einer radikal konstruktivistischen Linguistik und Grammatik
(Max Niemeyer Verlag, 1995)
Es scheint in der Linguistik wenigstens einen Archimedischen Punkt zu geben, wo der Linguist hintreten kann: Er kann davon ausgehen, daß der Gegenstand der Sprachwissenschaft die Sprache ist. Folglich kann der germanistische Sprachwissenschaftler davon ausgehen, daß der Gegenstand der germanistischen Sprachwissenschaft die deutsche Sprache ist. Folglich kann der germanistische Grammatiker davon ausgehen, daß der Gegenstand der germanistischen Grammatikschreibung die deutsche Grammatik ist. Aber was heißt das, daß der ...

Relativistic ab initio calculations for ion-atom collisions
(Richard, Patrick (Hrsg.), 1993)
Within the independent particle model we solve the time-dependent single-particle equation using ab initio SCF-DIRAC-FOCK-SLATER wavefunctions as a basis. To reinstate the many-particle aspect of the collision system we use the inclusive probability formalism to answer experimental questions. As an example we show an application to the case of S{^15+} on Ar where experimental data on the K-K charge transfer are available for a wide range of impact energies from 4.7 to 90 MeV. Our molecular adiabatic calculations and ...

Relativistic effects in physics and chemistry of element 105. [Part] I.
(American Institute of Physics, 1992)
A detailed study of the electronic structure and bonding of the pentahalides of group 5 elements V, Nb, Ta, and element 105, hahnium (and Pa) has been carried out using relativistic molecular cluster Dirac-Slater discrete-variational method. A number of calculations have been performed for different geometries and molecular bond distances. The character of the bonding has been analyzed using the Mulliken population analysis of the molecular orbitals. It is shown that hahnium is a typical group 5 element. In a great ...

Reduced L_1 level width and Coster-Kronig yields by relaxation and continuum interactions in atomic zinc
(1992)
Calculations of the level width \gamma( L_1) and the f_12 and f_13 Coster-Kronig yields for atomic zinc have been performed with Dirac-Fock wave functions. For \gamma(L_1), a large deviation between theory and evaluated data exists. We include the incomplete orthogonality of the electron orbitals as well as the interchannel interaction of the decaying states. Orbital relaxation reduces the total rates in all groups of the electron-emission spectrum by about 10-20 %. Different, however, is the effect of the continuum ...

Elastic nuclear scattering at intermediate and relativistic energies
(1990)
The classical scattering cross section of two colliding nuclei at intermediate and relativistic energies is reevaluated. The influence of retardation and magnetic field effects is taken into account. Corrections due to electron screening as well as due to attractive nuclear forces are discussed. This paper represents an addendum to [l].

Multiple vacancy inclusive probabilities for the scattering system 16 MeV S{^16+} on Ar
(1991)
To evaluate single and double K-shell inclusive charge transfer probabilities in ion-atom collisions we solve the time-dependent Dirac equation. By expanding the timedependent wavefunction in a set of molecular basis states the time-dependent equation reduces to a set of coupled-channel equations. The energy eigenvalues and matrix elements are taken from self-consistent relativistic molecular many-electron Dirac-Fock-Slater calculations. We present many-electron inclusive probabilities for different final configurations ...

Electronic structure and properties of the group 4, 5 and 6 highest chlorides including elements 104, 105, and 106
(1994)
Results of the Dirac-Slater discrete variational calculations for the group 4, 5, and 6 highest chlorides including elements 104, 105, and 106 have shown that the groups are not identical with respect to trends in the electronic structure and bonding. The charge density distribution data show that notwithstanding the basic increase in covalency within the groups this increase diminishes in going from group 4 to group 6. As a result, E106Cl_6 will be less stable toward thermal decomposition than WCl_6, which is confirmed ...

fürchten vs. ängstigen: Thematische Rollen und Ereignisstrukturen psychischer Verben ineinem Modell der Sprachproduktion
(infix-Verlag, 1999)
Die Abbildung außersprachlicher auf sprachsystematische Strukturen stellt für modulare Modelle der Sprachproduktion eine Herausforderung dar: So können scheinbar synonyme Verben ihre thematisch ausgezeichneten Argumente unterschiedlich syntaktisch positionieren: Hans ängstigt Maria oder Maria fürchtet Hans. Theoretisch-linguistische Abhandlungen deuten diese Divergenz als grammatische Eigenheit der Psych-Verben, welche entweder im Sinne einer lexikalischen Stipulation bzw. als Reflex syntaktischer Operationen beschrieben ...
