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 ...
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 ...
Aproximación semiclásica en la fotoionización por pulsos ultracortos asistidos por láser
(2019-05-28)
En esta tesis se estudia la ionización por encima del umbral (ATI) y la fotoionización asistida por láser (LAPE) de átomos y moléculas producida por campos láser ultra intensos y ultra cortos. En primer lugar, se considera ...
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 ...
Caracterización dosimétrica y monitoreo in situ para hadronterapia

Actualmente, se cuenta con modernas técnicas para el tratamiento del cáncer incluidas dentro del marco
de la radioterapia, conocidas como radioterapias no-convencionales. Estas técnicas fueron investigadas bajo el
mismo ...
