Coherent control with a short-wavelength Free Electron Laser
K. C. Prince, E. Allaria, C. Callegari +37
XUV and X-ray Free Electron Lasers (FELs) produce short wavelength pulses with high intensity, ultrashort duration, well-defined polarization and transverse coherence, and have bee…
Above-threshold ionization in neon produced by combining optical and bichromatic XUV femtosecond pulses
Nicolas Douguet, Alexei N. Grum-Grzhimailo, Klaus Bartschat
We consider the ionization of neon induced by a femtosecond laser pulse composed of overlapping, linearly polarized bichromatic extreme ultraviolet and infrared fields. In particul…
Electron-impact excitation of N using the B-spline R-matrix method: Importance of the target structure description and the size of the close-coupling expansion
L. Fernández-Menchero, O. Zatsarinny, K. Bartschat
There are major discrepancies between recent ICFT (Intermediate Coupling Frame Transformation) and DARC (Dirac Atomic R-matrix Code) calculations (Fernández-Menchero et al. 2014, A…
Quantum-mechanical calculations of cross sections for electron collisions with atoms and molecules
Klaus Bartschat, Jonathan Tennyson, Oleg Zatsarinny
An overview of quantum-mechanical methods to generate cross-section data for electron collisions with atoms and molecules is presented. Particular emphasis is placed on the time-in…
Displacement effect in strong-field atomic ionization by an XUV pulse
Igor A. Ivanov, Anatoli S. Kheifets, Klaus Bartschat +4
We study strong-field atomic ionization driven by an XUV pulse with a non\-zero displacement, the quantity defined as the integral of the pulse vector potential taken over the puls…
Hyperfine-changing transitions in He II and other one-electron ions by electron scattering
Klaus Bartschat, H. R. Sadeghpour
We consider the spin-exchange (SE) cross section in electron scattering from He\,{\scriptsize II}, which drives the hyperfine-changing \hbox{3.46 cm} (8.665 GHz) line transitio…
