Time-resolved observation of interatomic Coulombic decay induced by two-photon double excitation of Ne
T. Takanashi, N. V. Golubev, C. Callegari +46
The hitherto unexplored two-photon doubly-excited states [Ne()] were experimentally identified using the seeded, fully coherent, intense extreme ultraviolet…
Impact of intense laser pulses on the autoionization dynamics of the 2s2p doubly-excited state of He
Anton N. Artemyev, Lorenz S. Cederbaum, Philipp V. Demekhin
The photoionization of a helium atom by short intense laser pulses is studied theoretically in the vicinity of the doubly-excited state with the intention to investigat…
LCLS in - photon out: fluorescence measurement of neon using soft x-rays
Razib Obaid, Christian Buth, Georgi L. Dakovski +10
We measured the fluorescence photon yield of neon upon soft x-ray ionization (~1200 eV) from the x-ray free electron laser at Linac Coherent Light Source, and demonstrated the usag…
Neon in ultrashort and intense x rays from free electron lasers
Christian Buth, Randolf Beerwerth, Razib Obaid +3
We theoretically examine neon atoms in ultrashort and intense x rays from free electron lasers and compare our results with data from experiments conducted at the Linac Coherent Li…
Photoionization of hydrogen atom by coherent intense high-frequency short laser pulses: Direct propagation of electron wave packets on large spatial grids
Philipp V. Demekhin, David Hochstuhl, Lorenz S. Cederbaum
The time-dependent Schrödinger equation for the hydrogen atom and its interaction with coherent intense high-frequency short laser pulses is solved numerically exactly by propagati…
Kinetic Energy Release in Fragmentation Processes following Electron Emission: A time dependent approach
Ying-Chih Chiang, Frank Otto, Hans-Dieter Meyer +1
A time-dependent approach for the kinetic energy release (KER) spectrum is developed for a fragmentation of a diatomic molecule after an electronic decay process, e.g. Auger proces…
