Allowance for partial line overlap in determination of the optical thickness of a layer of plasma by the method of linear absorption

  • A. V. Rukosueva


  1. 1.

    The linear absorption has been calculated for two partly overlapping lines of Doppler form.

  2. 2.

    The linear absorption as a function of optical density has been calculated for the 5890 and 5896 Å lines of Na.

  3. 3.

    The concentration of Na atoms in a high-frequency discharge has been deduced by linear absorption and from the vapor pressure. The two sets of results are in satisfactory agreement.

  4. 4.

    Neglect of partial overlap can lead to results 50% too low in this case.
