摘要:

Expressions are developed for the electron density fluctuation spectrum for monochromatic radiation incident upon a magnetized plasma in thermal equilibrium. The method is based upon the full−wave derivation of a formal relation between the autocorrelations of particle density and dielectric tensor. Collisions are introduced into the formulation via a BGK and a Fokker−Planck collision term in the Boltzmann equation. An enhancement of the scattered spectra due to the excitation of longitudinal slow−wave resonances is predicted when the differential scattering vector is aligned primarily perpendicular to the magnetic field, provided that the collision−to−cyclotron frequency ratio satisfies the relation &ngr;/&OHgr; ≪ 1 in the BGK model or &ngr;/&OHgr; ≪ &OHgr;2m/k2KTin the Fokker−Planck model.
