The complex trajectory method in muon-induced prompt fission

The sensitivity of the muon attachment probabilities to the light fragments of prompt fission WL on the fission dynamics is discussed. It is shown that the final WL value consists of two contributions: one from the point of scission and a second from avoided crossing of the levels. It is therefore the second term which contains information about the prescission dynamics. The relative contribution from the prescission phase turns out to be higher for more asymmetric fission. Seeming discrepancies between various approaches noted in the literature find their natural reconciliation within the complex trajectory method.
