Bound on time-reversal noninvariance in the nuclear Hamiltonian
Journal Article

· Phys. Rev. Lett.; (United States)
Energy-level fluctuations are calculated by random-matrix methods, for time-reversal noninvariant (TRNI) Hamiltonians. The theory, applied to the data, shows that in the neutron and proton resonance regions, for heavy and intermediate nuclei (i.e., respectively), the local rms off-diagonal multiparticle H(TRNI) matrix element < or approx. = D/10, with D the level spacing. Spectral averaging methods reduce this to a bound on the nucleon-nucleon TRNI vs TRI interactions. First calculations, for /sup 169/Er, give a 1% upper bound.
