Abstract
Experimental results are presented which show that resonant mode coupling can be the dominant process in the scattering of cyclotron harmonic waves (or Bernstein modes). The important and new feature of the present work is that, in addition to confirming the frequency (energy) conservation relation ω1+ ω2 = ω3, the wavenumber (momentum) conservation relation k1 + k2 = k3 is also shown to be satisfied in accord with the requirements of resonant mode coupling [where ω1(k1) and ω 2(k2) refer to the incident waves and ω 3(k3) to the product wave]. Since all three waves participating in the scattering process are cyclotron harmonic waves, the present work provides an important technique for studying the symmetry relations which govern wave-wave scattering processes in a magnetic field.
