摘要: Abstract Measurements of the HeI line 41D − 21P, λ = 4921.93 A and its forbidden component 41F 4920.35 have been carried out for electron density range 7 × 1014 ≲ Ne (cm−3 3 1016. The lines were emitted from a continuous He afterglow plasma emerging plasmatron device with gas pressures ranging 100 torr to 2 atm. Our results are in general agreement measurements Birkeland et al., Nelson Burgess al. Wulff, but not new calculations Barnard
