Symmetry Violation in Heavy Nuclei
The advantage of searching for violation of Time Reversal Invariance in
neutron induced reactions using relative measurements of Time and Parity
violating effects is discussed. This approach gives the enhancement of
-violating effects by many orders of magnitude and, at the same time,
decrees theoretical uncertainties and experimental errors.Comment: 10 pages, invited talk at the workshop "Fundamental Physics with

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.Comment: talk at PANIC1
Sign correlations and the mechanism for parity violation
The problem of possible sign correlations of P-odd effects due to parity mixing on the compound nuclear stage is discussed. For an unambiguous test of the conventional model of parity violation on the compound nuclear stage, it is not enough only to measure the sign correlation of P-odd effects on some resonances, but it is necessary also to know the neutron decay amplitudes for each resonance
Parity violation in the n + 3He → 3H + p reaction: Resonance approach
The method based on microscopic theory of nuclear reactions has been applied for the analysis of parityviolatingeffects in few-body systems. Different parity-violating and parity-conserving asymmetries and theirdependence on neutron energy have been estimated for the n + 3He → 3H + p reaction. The estimated effectsare in a good agreement with available exact calculations
