Abstract

The effective relaxation of one-dimensional gravitational systems towards micro-canonical equilibrium is demonstrated in a series of computer experiments, the Kolmogorov-Smirnov goodness of fit test being used to give a measure of the evolution of the distribution function. The relaxation timescalet R is shorter thanNt C, and thus much shorter than the generally accepted estimatet R∼N 2tC,N being the number of particles in the system andt C a characteristic dynamical time.
