Abstract
Electromagnetic radiation is observed when an electron beam is injected into a uniform quiescent magnetoplasma. The emission peaks near the electron plasma frequency () and is found to result from the scattering of unstable intense electrostatic plasma waves off self-consistently produced ion acoustic waves with wave vectors . The emission is localized, polarized, and negligible in intensity at . Space-time growth and properties of the three-wave interaction are presented.
