Abstract
The effect of nonlinear Landau damping on the long term behaviour of the modulational instability of a monochromatic Langmuir wave has been investigated. The growth or decay of the perturbation amplitude is oscillatory in character. Most of the time the amplitude changes approximately linearly with time. Growth occurs for negative nonlinear frequency shift while it decays when the frequency shift is positive.
