Temperature dependence of Stark parameters for Fe I lines

Abstract

Stark broadening parameters of iron lines from the a 5G0 - e 5H multiplet (1146) and the z 3G0 - e 3H multiplet (1165) transition arrays are presented for temperatures ranging from 6500 to 14,100 K. Stark width is plotted against temperature for the Fe I 5383.371 A line. Temperatures, pressures, electron densities, and line profiles are determined and compared with experimental data.
