摘要: Abstract A theory is developed for the broadening of He I lines with forbidden components which valid at low densities (where line reasonably well isolated). This takes into account effects dynamic ion broadening. Application to λ4471A gives good agreement experiment and a recent calculation Lee; reasons Lee are discussed in detail. Comprehensive tables 4471A presented. These have been extended further wings than previous tabulations. Static found be adequate greater ∼ 5 × 10 15 cm −3 . simple numerical profile allowed lines, taking effects, also
