Observations with the NRL spectroheliograph $082A on board Skylab (Tousey et al., 1973) showed the presence of a large number of protrusions above the solar limb (the largest ones sometimes called 'superspicules'). These spicule-like features are especially well visible in the Le line of He + at 304

The inclusion of a frequencydependent collision operator in the line shape expression is investigated quantitatively for the 4471 A overlapping He1 line.
