Quantum Mechanical Calculations for the Electron Impact Broadening and Shift of the Line 43s → 23p of Helium in a Hot Plasma

Abstract

In this paper we apply the quantum mechanical formalism developed by Bassalo and Cattani to calculate the broadening and shift produced by electronic collisions of the43s → 23p line of helium in a plasma. The effect of the ions is also taken into account. Our theoretical predictions are compared with the experimental results of Bötticher et al. and with the semiclassical estimates of Griem et al.
