It is found that the nonlinear wave-particle interaction based on the single-wave model can be changed strongly by introducing effects of weak collisions into plasma electrons. These collisions are too weak to change the linear stage. However, they alter the phase relation between the single wave and the trapped electrons in the nonlinear stage. As a result, the wave amplitude of the first minimum decreases anomalously and the persistent trapped-particle oscillations in the collisionless case are destroyed.
