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 10¹⁷ 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).
