Abstract
The time-dependent and time-independent treatments of time delay in two-body scattering are discussed and shown to be completely equivalent. Further, we provide a careful discussion of the definition of time delay in both approaches. We are able to establish that the customary method of using an average limiting process is unnecessary if the time delay is evaluated between normalizable wave packets.Keywords
