Abstract

Bernstein wave interference patterns observed in an afterglow plasma are interpreted as being due only to electrostatic waves. Their effect is shown to be reduced to that of the two fields corresponding to the limit wave vectors of the undamped domain determined from the hot dispersion curves. The formulas obtained through this point of view yield the temperature of the medium and the theoretical amplitude of the field in agreement with the experimental signal envelopes.
