Stark width (W) and shift (d) of the neutral helium (He I)
381.96 nm spectral line in the high lying 
transition has been measured in the optically thin linear,
low-pressure, pulsed arc discharge operated in the helium at 50 000 K electron
temperature and 
m-3 electron density. These values are the first
experimentally obtained W and d related to this line. Unfortunately, comparison
with theoretical results is not possible due to the fact that only one existing
theoretical calculations has been
done at a 1019 m-3 electron density only. We have found
negative line shift (toward the blue) that agree well with existing theoretical predictions.
