The profiles of the BALMER- and PASCHEN-lines of hydrogen being emitted from a plasma of relatively low electron-density and temperature (Ne = 1.3 × 1013 cm-3, T=1 850 °K) are compared with theoretical profiles based on a quasistatic treatment of the ions and electrons. For a region extending from the line wing to a point lying well inside of HOLSTEIN’S frequency limit a satisfactory agreement with experiment can be achieved by using ECKER’S microfield-distribution folded with itself and by inserting values of the parameter r0/λ (r0≈mean particle distance, λ = DEBYE length) being roughly twice as high as one would calculate from the values of Ne and T. Within the framework of the quasi-static theory there seems to be no way of explaining the discrepancy between the high value of r0/λ which fits the experimental curves best and the theoretical value which is lower by a factor of about 2.
