The nodal structure of doubly-excited resonant states of helium (1991)
Rost, J., Gersbacher, R., Richter, Klaus, Briggs, J., Wintgen, Dieter
The authors examine the nodal structure of accurate helium wavefunctions calculated by direct diagonalization of the full six-dimensional problem. It is shown that for fixed interelectronic distance...
Semiclassical Cycle Expansion for the Helium Atom (1991)
Ezra, G., Richter, Klaus, Tanner, G., Wintgen, D.
The authors analyse the classical dynamics of near-collinear electron configurations in helium. The dynamics turns out to be fully chaotic. An application of periodic orbit quantization techniques...
Calculations of Planetary Atom States (1991)
Richter, Klaus, Wintgen, Dieter
The authors prove the existence of a new type of resonance formation in highly doubly excited atoms and ions. The resonant states represent the quantum analogue of a stable planetary atom...

Analysis of classical motion on the Wannier ridge (1990)
Richter, Klaus, Wintgen, Dieter
The authors study the classical electronic motion of a two-electron atom on the Wannier ridge. Stability properties of certain periodic orbits are calculated. The analysis shows that the helium atom...

Scaled-Energy Spectroscopy and Its Relation with Periodic Orbits (1988)
Eichmann, U., Richter, Klaus, Wintgen, Dieter, Sandner, W.
We show that the use of scaled variables in data recording leads to a simple but powerful parametrization of complicated spectra. In the case of the atomic Stark effect the parametrization is...

Stark effect on diamagnetic Rydberg states (1987)
Richter, Klaus, Wintgen, Dieter, Briggs, J.
The Stark effect on diamagnetic Rydberg states of hydrogen is investigated. In the perturbative regime, re-ordering of levels within a hydrogenic n manifold leads to level repulsion when the ratio of...
