Up: Stark profiles of infrared
We have calculated Stark widths and shifts for six infrared lines of
helium arising from highly excited levels. We have used the
Sahal-Bréchot theory and code which is well adapted to these
calculations. We have provided data in the impact and in the
quasistatic quadratic approximation. These data can be used for
modellisation of early-type stars.
