Interpretation of noncharacteristic M X-rays in heavy colliding systems by selfconsistent relativistic molecular calculations
(1976)
The result of the first calculation of a self-consistent relativistic many electron correlation diagram ever done (for the system Au - I) leads to a good agreement of the spectral shape and position of the observed noncharacteristic X-rays within the quasi adiabatic model.

Note on the quasimolecular M radiation in very heavy collision systems
(1976)
The quasimolecular M radiation emitted in collisions between Xe ions of up to 6 MeV energy and solid targets of Ta, Au, Pb and Bi, as well as a gaseous target of Pb(CH_3)_4, has been studied. Using a realistic theoretical correlation diagram, a semiquantitative explanation of the observed peak structure is given.

Auger spectroscopy of foil-excited beryllium ions
(Kleinpoppen, H. (Hrsg.), 1976)
We have measured prompt and delayed emission spectra of electrons from foilexcited Be, B^+, and Be^2+ ions at 300 keV. On the basis of recently calculated eigenvalues we identified two lines in the prompt Be^+ spectrum as transitions from 2s^22p and 2s2p^2. The delayed Be spectrum indicates that transitions from highly excited quintet states occur. We propose radiationless deexcitation with one excited spectator electron not involved in the transition.

Chemical and physical properties of superheavy elements
(1976)
A knowledge of the physical and chemical properties of superheavy elements is
expected to be of great value for the detection of these elements, owing to the
need for chemical separation in their isolation and identification. The methods
for predicting their electronic structures, expected trends in their chemical and
physical properties and the results of such predictions for the individual superheavy
elements are reviewed. The periodic table is extended up to element 172.

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.
