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 ...
