“…The Zwanzig projection operators should be redefined to include the effect of the statistical correlations (cf Ben-Reuven 1975) or the trace in equation (75) be calculated by other means. For example, whenever p is a grand canonical distribution, the method of finite-temperature (imaginary-time) Green functions of quantum field theory can be applied (Abrikosov et aI 1965, Fetter and Walecka 1971, Ross 1966, Bezzerides 1969a.…”

A tetradic scattering matrix formalism is proposed as a comprehensive framework for describing scattering and relaxation processes of both stationary and non-stationary systems. In the latter case (realized by the scattering of the molecular-maser beam) ordinary dyadic T-matrix formalism involving on-the-energy-shell scattering amplitudes is inadequate, the introduction of off-the-shell elements being required. Expressions are given relating the tetradic I-matrix elements to various scattering and attenuation rates (or cross sections). The relation to the tetradic level-shift operator in relaxation (linear response) theory is discussed. Photon absorption is presented as the successive occurrence of a scattering and a relaxation process, from the point of view of this formalism.
