Abstract
Quantum statistical approach is adopted for calculating the spectral line
shapes of neutral helium in dense plasmas. Stark broadening of isolated He
I lines 5048 Å (), 3889 Å (), and 3188Å ()
is presented. Based on thermodynamic Green's function, the electronic contribution to the shift and width is considered. The participation of ions to the line broadening is treated in a quasistatic approximation, by taking both
quadratic Stark effect and quadrupole interaction into account. The calculated shifts and widths are compared with existing data.
