Abstract: (1610 Views)
One of the main problems in laser-induced breakdown spectroscopy is self-absorption effect of emission spectral lines. To correct this effect, various solutions are proposed; in many of which knowing the amount of collision parameter, as the most important quantity, is essential in the Stark broadening of each line. In the present research work, collision parameter of the spectral line 393.36 nm related to once-ionized calcium (Ca II), for the first time, is determined using laser plasma spectroscopy and also other spectral lines of the species.
