摘要
Stark widths and shifts of Cr II lines with wavelengths in the range 2000-3500 angstrom 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 mu s, at which the temperature and electron density are in the ranges 12 000-16 300K and( 0.89-8.2) x 10(17) cm(-3), 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.
