Estudio y medida de las características iónicas de plasmas mediante espectrometría de masas
(Universidad de Córdoba, Servicio de Publicaciones, 2014)This work proposes a method to measure the Ii ? V characteristic of a plane probe for each one of the ion species present in a low-pressure plasma, by using a mass spectrometer as the ammeter whose probe entrance can ... -

Ionization probability of the hydrogen atom suddenly released from confinement
(Wiley, 2017)The problem of the stability of a confined atom when it is extracted from the confining cavity has been investigated, modeled by a spherical hard wall potential. The ionization probability when the atom is released from ... -
Polarization Properties of Laser Solitons
(MDPI, 2017)The objective of this paper is to summarize the results obtained for the state of polarization in the emission of a vertical-cavity surface-emitting laser with frequency-selective feedback added. We start our research with ... -
Microwave atmospheric pressure plasma jets for wastewater treatment: Degradation of methylene blue as a model dye
(Elsevier, 2017)The degradation of methylene blue in aqueous solution as a model dye using a non thermal microwave (2.45 GHz) plasma jet at atmospheric pressure has been investigated. Argon has been used as feed gas and aqueous solutions ... -
Ionization and excitation probabilities of a hydrogen atom suddenly released from penetrable confinement
(Taylor & Francis, 2018)The problem of the stability of the hydrogen atom when it is released from a confining environment is studied. The stability is analysed in terms of excitation and ionization probabilities of the final state for different ... -
A simple and accurate analytical model of the Stark profile and its application to plasma characterization
(Elsevier, 2018)Optical Emission Spectroscopy techniques are among the most employed to perform the characterization of laboratory plasmas. The analysis of the obtained data is based on the convolution of three different types of profiles: ... -
Singlet vs. triplet interelectronic repulsion in confined atoms
(Elsevier, 2018)Hund’s multiplicity rule invariably holds for the ground configurations of few-electron atoms as well as those of multi-electron quantum dots. However, the ordering of the corresponding interelectronic repulsions exhibits ... -
Simple and analytical function for the Stark profile of the Hα line and its application to plasma characterization
(Elsevier, 2018)The increasing application of plasma based technologies over a wide range of fields has led to the necessity of an optimal determination of the characteristic parameters of the plasma systems. Optical Emission Spectroscopy ... -
Quantum defect asymptotics at the critical charge: A study of the integrality conjecture
(Elsevier, 2018)A single (n, ℓ) electron outside an (N −1)-electron atomic core is bound as long as Z > Zc = N − 1. A conjecture is examined, according to which the quantum defect of the outermost electron satisfies limZ!Zc δn,ℓ(Z) = Nℓ, ... -
Stark Broadening of Se IV, Sn IV, Sb IV and Te IV Spectral Lines
(MDPI, 2018)Stark broadening parameters, line width and shift, are needed for investigations, análisis and modelling of astrophysical, laboratory, laser produced and technological plasmas. Especially in astrophysics, due to constantly ... -
Characterization of an Air-Based Coaxial Dielectric Barrier Discharge Plasma Source for Biofilm Eradication
(Springer, 2018)Air-based atmospheric-pressure cold plasmas are a source of charged particles, excited species, radicals, and UV rays, known to induce degradation of biomaterials. In this work we characterize an air-based Dielectric Barrier ... -
Exclusion Principle Repulsion Effects on the Covalent Bond Beyond the Born-Oppenheimer Approximation
(Royal Society of Chemistry, 2019)The changes in the covalent bond of the hydrogen molecule limited in the space by a spherical hard boundary are studied. The sphere is moved along an axis parallel or orthogonal to the molecular axis. The diffusion Monte ... -
