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 ...

Grundlagen und Verfahren medienorientierter Unterrichtsplanung
(1979)
The planning and organization of audio-visual instruction media are placed within a communication theoretical reference frame which begins where audio-visual media cease to function for daily instruction. Media-bound disorders however, are only seen as the surface conflict between opposing communication paradigms. The decisive task of the teacher is to remove audio-visual media from a communication context which is contradictory to instruction. This is successful when the objectification performance of audio-visual ...

Ethnomethodologie als handlungstheoretische Grundlage einer Didaktik der Kommunikation
(1979)
Our focus is the question as to how communication in school and instruction can be organized in an open-ended yet methodical fashion. Accordingly we proceed from the thesis that teaching methodology must be in accordance with the methodology od everyday activities so that school instruction can build on the structure of reflexive communication. We therefore adopt ethnomethodology as a theory of everyday activities in order to establish a repertoire of teaching methodologies. Taking an ethnomethodological perspective ...

Equilibrium K-shell excitation of highly ionized neon
(1979)
Augerelectron emission from foil-excited Ne-ions (6 to 10 MeV beam energy) has been
measured. The beam-foil time-of-flight technique has been applied to study electronic transitions of metastable states (delayed spectra) and to determine their lifetimes. To achieve a line identification for the complex structure observed in the prompt spectrum, the spectrum is separated into its isoelectronic parts by an Augerelectron-ion coincidence correlating the emitted electrons and the emitting projectiles of well defined final ...
