Scientific paper

Following their earlier work, and using a semiclassical-perturbation formalism for the Stark broadening of atomic lines, the authors have calculated electron and proton impact line widths and shifts of 36 neutral He lines. Stark broadening parameters were calculated for lines originating from upper energy levels with 4 ≤ n ≤ 10, and for an electron density of 1013 cm-3. The comprehensive set of results obtained is used for the investigation of line-broadening parameter regularities within the spectral series.
