The frequency and damping of ion-acoustic waves
Abstract
The paper considers the frequency and damping of ion-acoustic waves. The dispersion relation for a plasma with different ion and electron temperatures is solved numerically to obtain the frequency and the damping constant for ion-acoustic waves as a function of the wavenumber. It is shown that the commonly used expressions for these variables only apply if the temperature parameter T is larger than 20, and can lead to large errors if T is close to 1. Tables and graphs of the frequency and damping as functions of the wavenumber are given for different values of T.
