Abstract

The half-width and asymmetry parameter of the He I 21P–31D λ=667.8 nm line have been measured in a laser produced He plasma for electron densitiesN e between 7×1022 m−3 and 1.7×1023 m−3. Results, obtained for the half-width, agree very well with the theoretical results forN e ≲1023 m−3 and the agreement becomes somewhat worse forN e >1023 m−3. We have measured the red asymmetry which is considerable lower than the theoretical one. We have also established good agreement with theoreticalj A,R (x) profile for this line.
