Abstract
The profile of the He II λ = 4686 Å line has been measured in a plasma with an electron density of 5.5-1017 cm-3 and a temperature of 6 - 104 °K. The measured halfwidth is consistent with that predicted by the Griem and Shen theory. On the far wings the intensity approaches the value expected when ions and electrons are treated by the static theory, although the electrons are far outside the static broadening regime
