It is shown that under certain simple conditions, often nearly realized experimentally, the transition amplitudes in the distorted wave Born approximation theory of direct nuclear reactions have a simple symmetry under interchange of the distorted waves for initial and flnal states. For observations on the reaction, the symmetry is equivalent to rotating coordinate axes by n about the recoil direction. This property is used to show in detail how the initial and final distortions have opposing effects for some phenomena (such as polarization of emitted particles or change of symmetry axis for the distribution of subsequent gamma -rays) but are cooperative for others (such as the differential cross-section). Some conclusions are drawn abcut distortion effects in various types of reaction. (auth)
