Abstract

Both the definition of the term "fission channel" and the statistical properties of the relevant parameters of compound nuclear resonances, i.e. total and "partial" fission widths, are reviewed critically in close analogy to the description of nuclear reactions in general. It is concluded that a fission channel may be defined by the requirement that there should be no nuclear interaction in the channel. The fact that the statistical properties of resonance fission widths are decisively determined by some kind of doorway states, which probably have to be identified with Bohr's saddle point states (on top of the outer barrier), is not at variance with such a definition of fission channels, and is by no means a phenomenon restricted to the fission case.
