Stark broadening of Fe V spectral lines: 4s-4p transitions

International audienceUsing the impact semiclassical perturbation approach, widths and shifts of the 4s-4p configuration of Fe V spectral line profiles due to collisions with electrons, H + , He + and He 2+ ions, have been calculated in the physical conditions of hot white dwarfs. Energy levels and oscillator strengths needed for the calculation have been obtained by using the Hartree-Fock method with relativistic corrections. The results may be of interest not only for spectroscopic diagnostics in astrophysics, but also for laboratory plasmas, and technological plasmas. The obtained results will enter the STARK-B database which is in free access and which is a node of the Virtual Atomic and Molecular Data Center-VAMDC
