Stark-broadening studies of the N(I) multiplet 3p 4Po-3d 4D are reported. Our experimental electron impact widths of spectral lines are compared with the results of our calculations: (i) according to the standard impact theory of Griem with modification, (ii) using a computer simulation method which is based on numerical N-body code (CSM). Line shape measurements were performed using a wall-stabilized arc. The radiation of the plasma emitted from homogenous plasma layers was measured using a grating spectrometer equipped with a two-dimensional detector.

topics: Stark broadening, line shapes, optical measurements, computer simulations
