Many channel scatterirg is studied in a formulation general enough to be applicable, for example, to the scattering on bound systems by one another, such as in nuclear reactions, or to strange particle reactions in which incoming and outgoing particles have different masses. The assumptions made concerning the interaction potentials are relatively weak, no finite nuclear radius being assumed. Effects investigated include threshold phenomena and resonance scattering. Regarding the first, an alternative to the Wigner cusp is found. The Breit-Wigner resonance formula is rederived in a perturbation calculation which assumes neither large level spacings compared to the widths nor poles of the S matrix. It includes among the resonance terms only compound nucleus states, which are defined here uniquely bg means of the average particle interactions. (auth)
