“…The electron density is related to the line broadening, and for highly ionized and high density plasma, the collisions with charged particles present a strong electric field that produced a broadening of the transitions between the split atomic levels. These micro electric fields are associated with Stark broadening [14].…”

“…Intensities were normalized to unity to outline temporal evolution of profiles of the Cu I lines in The Cu 5105.54 Å line is significantly less affected by Stark effect, which was already pointed out in (Song et al 1999;Man et al 2004). The only one experimental values of Stark parameters of this line (Fleurier 1986) has the obvious discrepancy with theoretical data on Stark FWHM.…”

Stark effect is observed in many natural and artificial plasmas and is of great importance for diagnostic purposes. Since this effect alters profiles of spectral lines, it should be taken into account when assessing chemical composition of radiation sources, including stars. Copper is one of the elements which studies of stellar atmospheres deal with. To this end, UV and visible Cu lines are used. However, there is a lack of agreement between existing data on their Stark parameters. It is therefore of interest to obtain new experimental data on these lines and to compare them to previous results. In this work, we have estimated Stark widths and shifts for three blue-green lines at 5105.54, 5153.24, and 5218.20 Å (corresponding transitions are [3d 10 4p] 2 P° → [3d 9 4s 2 ] 2 D and [3d 10 4d] 2 D → [3d 10 4p] 2 P°) observed in a "long-spark" laser-induced plasma. For the first time, we have accurately estimated an impact of hyperfine splitting on the profile shapes of the studied lines taking also into account the isotope shifts. We have shown that both effects considerably influence shift and width of Cu I line at 5105.54 Å, and shifts of Cu I lines at 5153.24 and 5218.20 Å.
