Query: Time-Reversal Invariance Violation in Heavy and in Few-body Nuclei   Time reversal invariance violating (TRIV) effects in neutron scattering are
very important in a search for new physics, being complementary to neutron and
atomic electric dipole moment measurements. In this relation, a sensitivity of
TRIV observables to different models of CP-violation and their dependencies on
nuclear structure, which can lead to new enhancement factors, are discussed.
