Delocalization of a hole in van der Waals clusters: Ionization potential of rare-gas and small Hg_n clusters
(American Physical Society, 1993)
The size dependence of the ionization potential I_p(n) of van der Waals (vdW) bound clusters has been calculated by using a model Hamiltonian, which includes electron hopping, vdW interactions, and charge-dipole interactions. The charge-density and dipole-density distributions for both neutral and ionized n-atom clusters are determined self-consistently. The competition between the polarization energy of the neutral atoms surrounding a partially localized hole and the tendency toward hole delocalization in the ionized ...

Relativistic effects in physics and chemistry of element 105. [Part] IV.
(1993)
Results of relativistic (Dirac-Slater and Dirac-Fock) and nonrelativistic (Hartree-Fock-Slater) atomic and molecular calculations have been compared for the group 5 elements Nb, Ta, and Ha and their compounds MCl_5, to elucidate the influence of relativistic effects on their
properties especially in going from the 5d element Ta to the 6d element Ha. The analysis of the radial distribution of the valence electrons of the metals for electronic configurations obtained as a result of the molecular calculations and their ...

Das Kaiser-Friedrich-Museum und die Reform des Kunstmuseums
(1993)
Nach der Wiedervereinigung der Staatlichen Museen in beiden Teilen Berlins hat sich eine heftige Kontroverse über die Reorganisation und Zusammenführung der geteilten Museen entfaltet. In diesem neuen „Berliner Museumsstreit" nimmt das Bodemuseum auf der Museumsinsel, vor dem Krieg als Kaiser-Friedrich-Museum bekannt, einen zentralen Platz ein.
