Description
Starting from a three-wave interaction coefficient for a homogeneous Vlasov plasma, it is shown that the parametric decay to half-harmonics has zero growth rate if the wavenumber of the pump wave vanishes. Earlier proofs of this fact for electrostatic decay modes are thus extended for a general case. As a specific example, the decay of a fast magnetosonic wave to two slow waves is studied. (author)
