The quantum-statistical generalization of the well-known classical, linear revised
Enskog equation is derived for spatially uniform systems. This new quantum
kinetic equation allows the study of equilibrium time correlation functions and
their associated transport coefficients of normal quantum fluids where static
correlations and degeneracy effects due to particle statistics (both are treated
exactly) are important. Furthermore, we derive the quantum-statistical analog
of the classical ring operator. These microscopic and systematic derivations are
based on a recently developed superoperator formalism (including cluster
expansion techniques) that, as a main feature, allows a clear distinction between
static and dynamic correlations, which is crucial in the discussion of the Enskog
