Stark profiles of infrared helium lines

We have calculated Stark widths and shifts of some infrared helium lines th at are missing and that are important for modellisation of the atmospheres of hot early-type stars. These calculations are based on the impact and qua sistatic theory and semi-classical approximation. The provided data are dis played for a grid of temperatures (10(4) to 10(5) K) and electron densities (10(10) to 10(13) cm(-3)) typical of hot early-type stars. We also discuss the conditions of use of our data for astrophysical purposes.
