Stark broadened He I 3965 (4P-2S) has been studied experimentally using a plasma jet as a source. Integrated intensity profiles were obtained by scanning the cylindrically symmetric plasma across its width and using a spectrometer and optical multichannel analyser coupled to a magnetic tape drive system to record the profiles. The resulting data was converted to spectral line shapes as a function of plasma radius through the use of an Abel unfolding procedure carried out by a computer program. The radial dependence of the plasma temperature and density was determined and then used to match experimentally determined profiles with theoretical profiles which take the two forbidden components of the Stark broadened levels into account. Comparison of the experimental and theoretical profiles yielded good agreement. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
