Wechselwirkung von Ionen- und Elektronenwellen mit intensitätsgleicher Emission bei der einfachen und doppelten Plasmafrequenz

Abstract

Nonlinear interaction of longitudinal plasma waves in two-fluid plasma exciting the solar type II burst emission is investigated. The interaction of ion and electron waves yields radiation at the fundamental plasma frequency, while emission at twice the plasma frequency is caused by self-interaction of the electron waves. Equal flux intensity results in both the radiation bands if the variation of electron density associated with the two wave modes is of the same order of magnitude.
