The plasma containing the sodium atoms and the perturbers was generated in a hollow cathode discharge. The Baranger and Brechot theories for the line shape of neutral atom transitions in a plasma has been extended to hyperfine structure and applied to the hyperfine components of sodium D_1 line. The theoretical and experimental results were compared and the electronic density and temperature in the discharge were evaluated.engjournal articlehttp://dx.doi.org/10.1063/1.334238http://scitation.aip.org/open access535PhysicsAppliedÓptica (Física)2209.19 Óptica Física
