Data on Stark broadening parameters, spectral line widths, and shifts for 15 multiplets of N VI, whose spectral lines are broadened by collisions with electrons, protons, alpha particles (He III) and B III, B IV, B V and B VI ions, are presented. They have been calculated using the semiclassical perturbation theory, for temperatures from 50,000 K to 2,000,000 K, and perturber densities from 1016 cm−3 up to 1024 cm−3. The data for e, p and He III are of particular interest for the analysis and modelling of atmospheres of hot and dense stars, as, e.g., white dwarfs, and for investigation of their spectra, and data for boron ions are used for analysis and modelling of laser-driven plasma in proton–boron fusion research. Dataset: The dataset is submitted as a Supplementary File. Dataset License: CC-BY 4.0 [ABSTRACT FROM AUTHOR]

Stark broadening parameters, full widths at half-maximum of intensity and shifts for 18 spectral lines of Fe  xxv , broadened by collisions with electrons, protons, and Fe  xxvii ions, have been calculated using the impact semiclassical perturbation formalism for a grid of electron densities and temperatures of interest for neutron star atmospheres and their environment.
