Using a semiclassical approach, we have calculated electron-, proton-, and He III-impact line widths and shifts for 114 P IV multiplets for perturber densities tex2html_wrap_inline767 and temperatures tex2html_wrap_inline769. The obtained results have been compared with results obtained by using various simpler approaches.
