Despite the long history of neutron scattering studies on complex condensed matter systems, there is still a need for appropriate analysis concepts beyond the classical Van Hove theory, which is commonly used to interpret the experimental spectra in terms of trajectory-based dynamical models. The approach presented in this paper, which is based on quantum mechanical transition rather than on classical displacement probabilities, accounts by construction for the scattering kinematics and opens perspectives for the interpretation of quasielastic neutron scattering experiments from complex systems.
