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.
