Estudio de procesos de ionización múltiple en capas atómicas internas mediante espectroscopía de rayos X
(2016)
Conjuntamente con las líneas de diagrama presentes en un espectro de emisión de rayos x, existen líneas de menor intensidad llamadas líneas satélites. En esta tesis se realizó un estudio de este espectro satélite en muestras ...
Caracterización de mezclas de distintos compuestos de azufre mediante espectroscopía de emisión de rayos x /
(2010)
Se idearon métodos que permiten, mediante EPMA, diferenciar y cuantificar los compuestos presentes en una muestra (especiación). Para ello, se tomaron los espectros de rayos x emitidos por muestras preparadas con diferentes ...
Modelling of an Atmospheric–Pressure Air Glow Discharge Operating in High–Gas Temperature Regimes: The Role of the Associative Ionization Reactions Involving Excited Atoms
(MDPI AG, 2020-02)
A model of a stationary glow-type discharge in atmospheric-pressure air operated in high-gas-temperature regimes (1000 K < Tg < 6000 K), with a focus on the role of associative ionization reactions involving N(2D,2P)-excited ...
Multicenter continuum-distorted-wave eikonal-initial-state description of the electron-impact ionization of aligned H2 molecules
(American Physical Society, 2020-10-12)
In this work, the multicenter continuum-distorted-wave (CDW) eikonal-initial-state (EIS) model is introduced. In contrast to previously reported CDW EIS analyses for electron-molecule collisions, in which the ionized ...
Ionization of atomic hydrogen by electrons: the role of the contributions of the pseudo-states in the second Born approximation
(IOP Publishing, 2013-07-05)
The second Born approximation is often used, particularly when we study double processes such as the ionization?excitation and the double ionization of atoms and molecules by charged particles. But when we apply this ...
Ionization of atomic hydrogen by an intense resonant laser pulse
(Institute of Physics Publishing, 2009-12)
The ionization of atomic hydrogen by an intense laser field resonant with the transition ls-Spo is studied. The intensity of the field is strong enough to make the Rabi oscillations important. The theoretical treatment of ...
Ionization and double-excitations within the framework of the G-particle-hole hypervirial equation method
(John Wiley & Sons Inc, 2012-09)
Recently, through the use of one-electron excitation operators, the set of low-lying excited states of several electronic systems was obtained within the framework of the Hermitian Operator method combined with the ...
Interacción de electrones y protones con la materia. Caracterización del espectro de rayos x emitido por impacto de electrones y protones
(2017-11-10)
Se estudiaron espectros de rayos x de transiciones atómicas hacia las capas L, generados por impacto de electrones, en Fe, Ni, Ru, Ag y Te, utilizando para el análisis el software POEMA. Se determinaron parámetros atómicos ...
Glow Discharge in a High-Velocity Air Flow: The Role of the Associative Ionization Reactions Involving Excited Atoms
(Molecular Diversity Preservation International, 2019-08)
A kinetic scheme for non-equilibrium regimes of atmospheric pressure air discharges is developed. A distinctive feature of this model is that it includes associative ionization with the participation of N(2D, 2P) atoms. ...
