Collision Damping of Plasma Oscillations. I

Collision damping of long-wavelength electrostatic oscillations in a high-temperature plasma is studied with the use of Guernsey's kinetic equation. A closed expression for ${\gamma }_C\mathrm{}\left(k\right)\mathrm{}$, the collision damping decrement, is derived which is exact to first order in the plasma parameter, $\frac{{k_D}^3}{n}$.
