New calculations of Stark pr ofiles of neutral helium lines

New Stark broadening calculations of He I triplet lines 1s2p 3 P-1snd 3 D with n=8-20 are presented for electron densities and temperatures covering tokamak divertor conditions. The calculations are based on the standard broadening theory which consists on the use of the impact and the quasi-static approximations for the interactions of the emitter with the plasma electrons and ions respectively. More precisely, we have used for the electrons a binary model and for the ions the Holtsmark field distribution. An atomic physics data basis of neutral helium has been constructed using hydrogen wavefunctions to calculate the dipole transition matrix elements. The aim of these line profile calculations is to demonstrate their possible use for diagnostic purposes in divertor plasmas containing neutral helium.
