Abstract
An interesting feature of compound nucleus reactions is that they enhance violations of fundamental symmetries (parity and time reversal). This fact has repeatedly been pointed out in the framework of a two-resonancemodel. Two resonances — isolated from all others — do not exist in nuclei. Here, this objection is investigated in a statistical sense. It is shown that the two-level-model yields results that are partly identical, partly quite similar to those from the multi-level-model.
