Stark broadening parameters, widths, and shifts for 33 singlets and 37 triplets were calculated using the semiclassical perturbation method. The results were compared with available experimental and theoretical data. Also, regularity in the spectral series 5s2 1S–np 1P° was investigated. The influence of Stark broadening was analyzed in A-type stellar atmospheres.
