A simple and accurate analytical model of the Stark profile and its application to plasma characterization
Díaz Soriano, Antonio Manuel; Alcaraz Pelegrina, José Manuel; Sarsa, A.; Dimitrijević, Milan S.; Yubero, Cristina (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: ... -
An off-center endohedrally confined hydrogen molecule
Morcillo Arencibia, Milagros Francisca; Alcaraz Pelegrina, José Manuel; Sarsa, A.; Randazzo, Juan M. (Royal Society of Chemistry, 2022)In this study, we address the problem of a C60 endohedrally confined hydrogen molecule through a configuration–interaction approach to electronic dynamics. Modeling the confinement by means of a combination of two Woods–Saxon ... -
Confined orbitals in fullerenes and quantum dots calculated by analytic continuation method
Morcillo Arencibia, Milagros Francisca; Alcaraz Pelegrina, José Manuel; Sarsa, A. (Springer, 2021)The Schrödinger equation with a Gaussian potential to model a confined system as a quantum dot or a hydrogen atom inside a fullerene is solved by using the analytic continuation method. The use of the Rodrigues formula ... -
Effects of size on the spectrum and stability of a confined on-center Hydrogen atom
Morcillo Arencibia, Milagros Francisca; Sarsa, A.; Alcaraz Pelegrina, José Manuel (IOP Publishing, 2022)In this work we studied the problem of the stability of confined atoms when they are released from confinement. We analyzed the confined Hydrogen atom inside a cage modelled by a square-well potential, in particular the ... -
Exclusion Principle Repulsion Effects on the Covalent Bond Beyond the Born-Oppenheimer Approximation
Sarsa, A.; Alcaraz Pelegrina, José Manuel; Le Sech, C. (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 ... -
Ionization and excitation probabilities of a hydrogen atom suddenly released from penetrable confinement
Morcillo Arencibia, Milagros Francisca; Alcaraz Pelegrina, José Manuel; Sarsa, A. (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 ... -
Ionization probability of the hydrogen atom suddenly released from confinement
Morcillo Arencibia, Milagros Francisca; Alcaraz Pelegrina, José Manuel; Sarsa, A. (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 ... -
On- and off-center helium atom in a spherical multilayer quantum dot with parabolic confinement
Morcillo Arencibia, Milagros Francisca; Alcaraz Pelegrina, José Manuel; Sarsa, A.; Randazzo, Juan M. (Springer, 2023)The ground state energy of a helium atom inside a spherical multilayer quantum dot as a function of the atomic impurity location inside the quantum dot has been calculated. The multilayer quantum dot is modeled by a ... -
Simple and analytical function for the Stark profile of the Hα line and its application to plasma characterization
Díaz Soriano, Antonio Manuel; Dimitrijević, Milan S.; Alcaraz Pelegrina, José Manuel; Sarsa, A.; Yubero, Cristina (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 ... -
Stability after confinement of the H atom
Morcillo Arencibia, Milagros Francisca; Borja, Enrique F.; Alcaraz Pelegrina, José Manuel; Sarsa, A. (Elsevier, 2019)The stability of a spherically confined atomic system when confinement is removed is studied. We consider s, p, d, and f states of the Hydrogen atom confined by a finite barrier. The stability is characterized in terms of ...
