Damping of ion acoustic waves in a plasma with rare collisions in connection with nonlocal hydrodynamics
Maksimov A. V., Silin V. P.
An expression for the damping rate of ion acoustic waves is derived from a solution of the electron kinetic equation corresponding to a fractional-asympototic expansion in reciprocal values of the Knudsen number. Some consequences of the hydrodynamics of Grad moments in a model of a nonlocal electron thermal conductivity are discussed.
