    Experimental Stark widths and shifts of MnII spectral lines
    (Oxford University Press, 2019) Manrique Rosel, Javier; Aragón Garbizu, Carlos; Aguilera Andoaga, José Antonio; Zientziak; Institute for Advanced Materials and Mathematics - INAMAT2; Ciencias
    Stark widths and shifts of MnII lines with wavelengths in the range 2300-3500 Å have been measured by laser-induced breakdown spectroscopy. The use of fused glass samples with varying Mn concentrations has allowed minimization of the error due to self-absorption in the Stark width measurements, which has made it possible to include resonance lines in the study. The laser-induced plasmas are characterized along their temporal evolution, showing electron densities in the range (0.60-6.75)×1017 cm-3 and temperatures in the range 11 000-13 900 K. The results are compared with experimental and theoretical values available in the literature.

    Experimental stark widths and shifts of V II spectral lines
    (Oxford University Press, 2020) Manrique Rosel, Javier; Díaz Pace, D. M.; Aragón Garbizu, Carlos; Aguilera Andoaga, José Antonio; Zientziak; Institute for Advanced Materials and Mathematics - INAMAT2; Ciencias
    We have measured the Stark widths and shifts of V II spectral lines in the wavelength range 2000-4200 Å belonging to 75 multiplets. The spectra are emitted by laser-induced plasmas generated from fused glass discs prepared by borate fusion. The electron density and temperature are in the ranges (0.72-6.5) × 1017 cm-3 and (11 000-14 900) K, respectively. To avoid self-absorption, we have used seven samples with vanadium concentrations selected by the CSigma graph methodology. This has allowed to include strong and weak lines in the study, including resonance and forbidden lines. The experimental widths and shifts are compared with theoretical values available in the literature.

    Experimental Stark widths and shifts of Cr II spectral lines
    (Oxford University Press, 2013) Aguilera Andoaga, José Antonio; Aragón Garbizu, Carlos; Manrique Rosel, Javier; Física; Fisika
    Stark widths and shifts of Cr II lines with wavelengths in the range 2000–3500 Å have been determined by laser-induced breakdown spectroscopy. The spectra have been measured at different instants of the plasma evolution from 0.6 to 3.4 μs, at which the temperature and electron density are in the ranges 12 000–16 300 K and (0.89–8.2) × 10¹⁷ cm ˉ³, respectively. The laser-induced plasmas have been generated from three fused glass samples with different chromium concentrations, selected to control the self-absorption of the lines. The Stark widths and shifts are compared with the experimental and theoretical data available in the literature.
