Stark widths of Sc IV spectral lines within 4s-4p transition array

Abstract

Stark full widths at half maximum of six 4s -4p Sc IV spectral lines, broadened by collisions with electrons, have been calculated for electron density of 10 17 cm −3 by using the modified semiempirical method. The results are provided for temperatures from 10 000 K to 160 000 K. They are used also to discuss the similarities of Sc IV spectral lines within multiplet, supermultiplet and transition array. Obtained results will be included in the STARK-B database which is also a part of Virtual atomic and molecular data center(VAMDC).

On the Stark broadening of Ru III spectral lines

“…Among different line broadening mechanisms, Stark broadening due to interaction of emitter/absorber with surrounding charged particles has many useful applications in astrophysics (see e.g. Dimitrijević (2017)), as well as for laboratory plasmas investigation and especially diagnostics. Stark broadening data are also useful for different investigations and modelling of fusion plasma, laser produced plasma diagnostic and analysis, as well as for its different applications in industry and technology as for example for welding, melting and piercing of metals by laser produced plasmas (see for example Dimitrijević (2017) and references therein).…”

Such data are also needed for design and development of light sources using different plasmas , as well as for development of laser devices.…”

“…In order to provide some of the needed data we calculated here Stark full widths at half maximum (FWHM -W) and shifts the for six multiplets in Corresponding author: mdimitrijevic@aob.rs PHYSICS the spectrum of doubly charged ruthenium ion by using the simplified modified semiempirical method -SMSE (Dimitrijević & Konjević, 1987). Additionally, for two multiplets, for which is possible to apply the full modified semiempirical method -MSE (Dimitrijević & Konjević, 1980;Dimitrijević & Kršljanin, 1986;Dimitrijević & Popović, 2001), analyzed in Dimitrijević (2017). The results obtained using both methods are compared in order to test the accuracy of SMSE method.…”
