A general and concise formalism is presented for the identification and evaluation of observables, including those that would indicate parity-conservation and/or time-reversal violation by the neutron-nucleus interaction, of experiments on the transmission of polarized neutrons through polarized nuclear targets. Statistical tensors are used for the description of the polarization states of the projectile and target, and the neutron-nucleus total cross section is decomposed into partial cross sections so that each corresponds to different ranks of the projectile and target statistical tensors and to a specific transfer of the orbital angular momentum. Each such partial cross section is associated with a correlation factor'' of particular parity-conservation and time-reversal symmetries, and is measurable by polarizing the projectile and target in states in which the statistical tensors have specific geometries, suggested by the simple geometric properties of the correlation factors.
