Abstract
Curvilinear trajectory adiabatic approxination for calculating Stark broadening parameters for neutral lines from plasmas, as proposed by authors,1,2 has been applied to HeI(31p0-21S ) line, at T = 5000. K and Ne=1015cm-3. This line has been chosen for two reasons: (1) The quadrupole perturber-emitter interaction potential is much smaller than corresponding dipole polarization interaction, so that simple analytical calculations can be carried out; (2) Stark constant C4 of the upper level of the transition is negative and large, so that so called defocusing effect can be distinctly demonstrated.
