“…There has been only a few investigations of the role of cyclotron motion in Stark broadening models. An early work using a collision operator model [3][4][5] has indicated the possibility for an alteration of the line broadening. This issue has also been considered recently in [6] using another collision operator model and, last year, a set of standardized cases was devoted to this issue at the fourth edition of the Spectral Line Shape in Plasmas (SLSP) Code Comparison Workshop (see http://plasma-gate.weizmann.ac.il/projects/slsp/slsp4/ and References [7,8] for an overview of this workshop).…”

In plasmas subject to a strong magnetic field, the dynamical properties of the microfield are affected by the cyclotron motion, which can alter Stark-broadened lines. We illustrate this effect through calculations of the hydrogen Lyman α line in an ideal one-component plasma. A focus is put on the central Zeeman component. It is shown that the atomic dipole autocorrelation function decreases more slowly if the cyclotron motion is retained. In the frequency domain, this denotes a reduction of the line broadening. A discussion based on numerical simulations and analytical estimates is done.

“…The effects of magnetic fields on Stark-broadened hydrogen Balmer lines along with a new method for measuring electron densities from these line profiles in strongly magnetized plasmas has been proposed (Ref. 93). The range of electron densities investigated were from 3 x 10 15 to 1 x 10 16 electrons/cm 3 .…”
