Abstract:
The asymmetric self-reversed resonance neutral aluminum and copper atoms spectral lines have been investigated at the high electron concentrations under the conditions of an impulse capillary discharge in the air. The recorded asymmetry of Al I 394.4 and 396.1 nm lines are in good agreement with the literary values of the Stark broadening parameters. Those lines may be recommended for the plasma electron concentration determination. At first the Stark broadening parameters of the copper atoms Cu I 324.7 and 327.4 nm lines have been determined by their asymmetric self-reversal parameters.
Keywords:plasma, spectral line, Stark broadening, self-reversal, electron concentration.
