摘要: Accurate profiles of the astrophysically important He I 4471 AA transition and its associated forbidden component have been obtained for first time in a laboratory plasma independently known electron density at values comparable to those B-class stars. Comparison experimental with most recent accurate theoretical predictions shows very good agreement halfwidth profile allowed far wing component, but considerable discrepancy exists between intensity near peak component.
