Abstract
We examine the space-time symmetries of forward 2 --> 2 scattering. Th ese symmetries have non-trivial consequences for any class of configur ations which might dominate the amplitude in the semiclassical approxi mation. We derive some dynamical results regarding the stability of co nfigurations which arise solely from reflection symmetry and positivit y of the (Euclidean) path-integral action. We consider the relative im portance of initial state effects on non-O(3) symmetric configurations .
