• The profiles of neutral helium lines at .), 4471, 4921, 5016, 6678, and 7065 A wereobserved in a plasma of electron density 1.0 to 3.5 x 10" cm ' generated in animproved T-tube. Comparison of the measured profiles with the profiles predicted by line broadeningtheories shows that the /. 7065 A line is well described by the isolated line appro,xi-mation but the 2 5016 and 6618 A lines should be treated by the overlapping line theoryin a plasma of electron density of 3.0 x 10" cm '. On the profile of the 2 4471 A linewhich has intense forbidden components, disagreement between the observed and thetheoretical result is seen on the wavelength separation between the allowed and theforbidden component. The observed ratio of the maximum intensity of the forbiddencomponent to that of the allowed component is larger than the theoretical ratio.
