Let ..cap alpha.. be the relative norm of a symmetry-breaking term in the Hamiltonian of a many-particle system, and ..lambda.. the energy-dependent transition parameter which charcterizes the quantum chaos via spectral and strength fluctuations. Combining a compact theory for ..lambda../..cap alpha../sup 2/ with fluctuation theories by which ..lambda.. can be deduced from (neutron-resonance) data gives, for the time-reversal-noninvariant nucleon-nucleon interaction, ..cap alpha..less than or equal to(1--2) x 10/sup -3/, which would improve with better small-strength data in nuclei with dense spectra. Diffusion equations involving ..lambda.. as the ''time'' variable are also discussed.
