ION-SCATTERING FROM STRONG TURBULENCE WITH LONG-RANGE CORRELATIONS

Colliding plasmas can excite strong Langmuir turbulence in which colle ctive correlations affect the probability distribution P(E) of the ele ctric microfield. This can be modeled by including long-range correlat ions but not dynamics over lengths much greater than lambda(D). Earlie r work yielded a characteristic distribution P(E) is-proportional-to E (d-1) exp(-E2/<E2>), with d the dimensionality of the electric field a nd [E2] proportional to the square of the correlated particle density. Ions scatter from this localized strong turbulence at rates greatly e xceeding classical collisions for solar coronal conditions, while labo ratory ion beams have no appreciable scatter beyond the Coulomb rate.
