It is found that the power-law structure persists even after the system is virialized. The structure gradually disappears owing to energy exchange among particles. Energy distribution is quasi-stationary after the system is virialized.10 pages, 6 figures, to appear Physics Letters AAstrophysicsChaotic Dynamicstext
