Multicolor XUV above threshold ionization of Argon
(IOP Publishing, 2015-10-23)
Argon photo-electron spectra produced by short-pulse extreme ultraviolet radiation, and with particular emphasis on the two-photon absorption region, is analyzed theoretically. The electromagnetic pulse is modeled to ...
Angularly resolved two-photon above-threshold ionization of helium
(American Physical Society, 2019-02)
Angularly resolved two-photon single ionization yields of helium resulting after the interaction with an ultrashort XUV pulse are obtained by numerically solving the full dimension time-dependent Schrödinger equation. The ...
Positronium ionization by short UV laser pulses: Splitting of the ATI peaks by Rabi oscillations
(Elsevier Science, 2006-12)
The interaction between positronium and a short laser pulse is studied in the case, where the photon energy is resonant with the 1s → 2p transition energy. Results from a full numerical solution of the time-dependent ...
Sequential and direct two-photon double ionization of D2 at FLASH
(Institute of Physics Publishing (IOP)Grupo de Física Atómica y MolecularReino Unido, 2018)
Using ultrashort xuv laser pulses to investigate symmetry breaking in one-photon single-ionization of H2
(Institute of Physics Publishing (IOP)Grupo de Física Atómica y MolecularReino Unido, 2020)
Chemodynamics of green pea galaxies - I. Outflows and turbulence driving the escape of ionizing photons and chemical enrichment
(Wiley Blackwell Publishing, Inc, 2020-05)
We investigate the ionized gas kinematics, physical properties, and chemical abundances of Sloan Digital Sky Survey J142947, a Green Pea galaxy at redshift z ∼ 0.17 with strong, double-peak Ly α emission and indirect ...
Sub-Poissonian angular momentum distribution near threshold in atomic ionization by short-laser pulses
(American Physical Society, 2008-12)
We analyze the angular momentum distribution of electrons near threshold in atomic ionization by short laser pulses. The radial fanlike pattern in the two-dimensional momentum distribution observed in experiments is ...
Intra- and intercycle interference of angle-resolved electron emission in laser-assisted XUV atomic ionization
(IOP Publishing, 2018-02)
A theoretical study of ionization of the hydrogen atom due to an XUV pulse in the presence of an infrared (IR) laser is presented. Well-established theories are usually used to describe the laser-assisted photoelectron ...
Double-bound equivalent of the three-body Coulomb double-continuum wave function
(American Physical Society, 2007-03)
In cross-section calculations of electron or photon double ionization processes of two-electron atoms, it is desirable to have a symmetric description of initial and final states. In this contribution, we search the doubly ...
Electronic Properties and Dissociative Photoionization of Thiocyanates, Part III. the Effect of the Group's Electronegativity in the Valence and Shallow-Core (Sulfur and Chlorine 2p) Regions of CCl3SCN and CCl2FSCN
(American Chemical Society, 2017-12)
Both photoelectron spectroscopy (PES) data and PhotoElectron-PhotoIon-Coincidence (PEPICO) spectra obtained from a synchrotron facility have been used to examine the electronic structure and the dissociative ionization of ...
