U.S.A. 14 629 Plasma Oscillations.—If..we change the concentration of electrons by some transient external means, the resulting electric fields act..to equalize the concentration, but the potential energy of these fields is converted into kinetic energy of the electrons so that oscillations occur, and electric waves may result. 1970 W. A. Harrison Solid State Theory iii. 288 Physically these plasma oscillations correspond to soundlike compression waves in the electron gas. 1992 S. P. Maran Astron. & Astrophysics Encycl. 631/2 The fastest CMEs do show a good (but not perfect) correlation with reported metric type II bursts, the slow-drift bursts attributed to coronal plasma oscillations at an expanding shock front. < as lemmas |
