Description

An analysis is made of the self-modulation of large amplitude Langmuir waves due to weak relativistic corrections to the plasma frequency and also to the nonlinear coupling of the wave with ion quasi-modes. It is shown that the wave is unstable to long wavelength perturbations with the instability occurring in the kinetic regime where (sup(Me)sub(mi))(sup(Ti)sub(Te) ≅ k2λ2sub(DE) which is different to the quasi-static or hydrodynamic regimes.
