Two-center resonant photoionization-excitation driven by combined intra- and interatomic electron correlations
S. Kim, S. Steinhäuser, A. B. Voitkiv +1
Ionization-excitation of an atom induced by the absorption of a single photon in the presence of a neighbouring atom is studied. The latter is, first, resonantly photoexcited and,…
Resonantly enhanced interatomic Coulombic electron capture in a system of three atoms
S. Remme, A. B. Voitkiv, C. Müller
In interatomic Coulombic electron capture, the capture of a free electron at an atomic center is accompanied by the radiationless transfer of the excess energy to a neighboring ato…
Relativistic strong-field ionization of hydrogen-like atomic systems in constant crossed electromagnetic fields
A. Eckey, M. Klaiber, A. B. Voitkiv +1
Relativistic strong-field ionization of hydrogen-like atoms or ions in a constant crossed electromagnetic field is studied. The transition amplitude is formulated within the strong…
A measurement of the evolution of Interatomic Coulombic Decay in the time domain
F. Trinter, J. B. Williams, M. Weller +17
During the last 15 years a novel decay mechanism of excited atoms has been discovered and investigated. This so called ''Interatomic Coulombic Decay'' (ICD) involves the chemical e…
Resonantly enhanced photoionization in correlated three-atomic systems
B. Najjari, C. Müller, A. B. Voitkiv
Modifications of photoionization arising from resonant electron-electron correlations between neighbouring atoms in an atomic sample are studied. The sample contains atomic species…
Electron correlation and interference effects in strong-field processes
Markus C. Kohler, Carsten Müller, Christian Buth +5
Several correlation and interference effects in strong-field physics are investigated. We show that the interference of continuum wave packets can be the dominant mechanism of high…
