We report measured Stark shifts and widths of the neutral carbon 5052- and 4932-A lines and the neutral oxygen 4368-A line in the plasma of an atmospheric pressure wall stabilized electric arc. Electron densities of (1.4--3.1)[times]10[sup 16] cm[sup [minus]3] are measured from the width of the H[sub [beta]] line while electron and gas temperatures in the range from 9300 to 10 300 K are determined from plasma composition data. Experimental Stark widths and shifts are compared to theoretical results obtained from semiclassical calculations of Stark broadening parameters using quasistatic and ion-dynamic treatment of the ions. Some indications are found that the inclusion of ion dynamics in the calculation of the shifts of the C I 5052-A line slightly improves the consistency between theory and experiment.
