The three-body time-delay operator
T. A. Osborn, D. Bollé
Using Faddeev’s form of time-dependent scattering theory, we give an abstract definition of time delay valid for multichannel scattering. For the three-body scattering problem we find an explicit relation, that is valid on the energy shell, between the time-delay operator and the S operators and their energy derivatives.
