A Time-Asymmetric Process in Central Force Scatterings    [PDF]

Ramis Movassagh

We show that in attractive force fields a high speed particle with a small mass speeding through space, statistically loses energy by colliding softly and transversely with large masses that move slowly and randomly. Furthermore, we show that the opposite holds in repulsive force fields: the light particle statistically gains energy. We consider the large masses to be distant from one another such that a series of two-body scatterings would suffice for the statistical analysis. The difference of this process from equilibration is discussed.
