On the decay of a dipole pump to half-harmonicsFunded under: FP2-FUSION 10C
Starting from a three-wave interaction coefficient for a homogeneous Vlasov plasma, it is shown that the parametric decay to half-harmonics has a zero growth rate if the pump wave wavenumber vanishes. Earlier proofs of this fact for electrostatic decay modes are extended to the general case. As a specific example, the decay of a fast magnetosonic wave to two slow waves is studied.
