Abstract
Instability of electrostatic ion shock waves has been induced by producing an inhomogeneity in the plasma ahead of the wave. A process based on nonlocal instability of precursor ions ejected ahead of finite-amplitude waves is proposed. In addition, instabilities of large-amplitude ion-acoustic waves have been observed and are ascribed to a similar process.Keywords
