Data on spectral line widths and shifts broadened by interactions with charged particles, for 44 lines in the spectrum of ionized tin, collisions electrons H II HeII ions, are presented as online available tables. We obtained them employing semiclassical perturbation theory temperatures, T, within 5000–100,000 K range, a grid perturber densities from 1014 cm−3 to 1020 cm−3. The Stark broadening data interest analysis synthesis tin spectra hot dense stars, such as, example, white dwarfs...

For a microwave plasma at atmospheric pressure the use of Stark broadening H α , β and γ lines to determine electron density temperature is reported. Knowing values these parameters important because electrons (density) their energy (temperature) control internal kinetics in discharge. We found that Gigosos–Cardeñoso model permitted us obtain same value from three Balmer lines. The dependence on for has application an intersection method try finding simultaneously. results have shown...

Surface wave plasma at atmospheric pressure has been used to produce the decomposition of alcohol molecules introduced into it, in order obtain hydrogen. Four alcohols, methanol, ethanol, propanol and butanol, have for this purpose. Optical emission spectroscopy was tool analyse radiation emitted by plasma. Hydrogen atoms other species such as C2 CH alcohols detected but no CO molecular bands. Also, a mass spectrometer detect hydrogen production methanol decomposition.

A surface-wave-sustained discharge created by using a surfatron device in tube open to the atmosphere can be used maintain microwave (2.45 GHz) plasma at atmospheric pressure powers of less than 300 W. The TIA ( Torche à Injection Axiale) is also producing that, moreover, permits us work high power (higher 200 W and up 1000 W). study departure from thermodynamic equilibrium existing argon plasmas both devices has been done optical emission spectroscopy techniques order characterize them...

Stark broadening parameters, line width and shift, are needed for investigations, analysis modelling of astrophysical, laboratory, laser produced technological plasmas. Especially in astrophysics, due to constantly increasing resolution satellite borne spectrographs, large terrestrial telescopes, data on trace elements, which were previously insignificant, now have importance. Using the modified semiempirical method Dimitrijević Konjević, here, widths been calculated 2 Se IV, 6 Sn Sb IV 1 Te...

The spectroscopic method for gas temperature determination in argon non-thermal plasmas sustained at atmospheric pressure proposed recently by Spectrochimica Acta Part B 129 14 (2017)—based on collisional broadening measurements of selected pairs atomic lines, has been applied to other and the discrepancies found some these results have analyzed. For validation purposes, values obtained using different lines compared with rotational temperatures derived from OH ro-vibrational bands,...

Cold atmospheric argon plasma jets have shown to be very promising in medicine and they are being currently used for therapeutical uses such as the healing of wounds or treatment tumors. Because run open atmosphere, generate copious amounts reactive oxygen nitrogen species, which play an outstanding role their biological action. But, this kind reactor, unknown air enter region depending on experimental conditions, changing chemistry them, eventually effects. In work, we propose a new...

In this work, we present a new method allowing the determination of both gas temperature and air fraction in non-thermal atmospheric helium plasmas. This UV-Atomic Emission Spectroscopy technique based on measurement collisional broadening He I 667.82 nm 728.13 emission lines is particularly sensible under low conditions; hence it suitable for diagnosis cold plasmas biomedical use. To quantify unknown amount entering these plasma jets key to understanding chemistry them basis their clinical...

Laboratory plasmas can be characterized by Optical Emission Spectroscopy techniques using Hydrogen Balmer series lines. The line shape is the result of convolution several internal process occuring in plasma. Stark effect over emitter atom has been studied a limited range plasma parameters, obtaining profile which sum given number Lorentzian functions for Hα and Hβ line. In this paper, we have extended analysis to cover wide conditions depends on contribution ion collisions around their...
