Stability of Shell Distributions.
Abstract
Stability criteria for parallel propagating plasma waves driven unstable by a nearly isotropic bump-in-energy half-shell beam of electrons along a magnetic field are investigated. Comparison with the drifting Maxwellian at equal densities reveals smaller growth rates for the half-shell and a shift in the unstable wave numbers towards smaller phase velocities. The limit of complete isotropy is stable to the waves under consideration. (Author)
