Compound-nuclear tests of time reversal invariance in the nucleon-nucleon interaction

Conference ·
OSTI ID:5855321
; ;
The theory for the effects of time-reversal noninvariance (TRNI) in complex systems is reviewed. Applied to the compound-nuclear data for energy-level, width and cross-section fluctuations (the latter for detailed-balance pairs of reactions proceeding through the compound nucleus) this gives bounds on multiparticle TRNI Hamiltonian matrix elements. Using a fluctuation-free form of statistical spectroscopy the results are reduced to bounds on ..cap alpha.., the relative magnitude of the TRNI nucleon-nucleon interaction. The level and width analyses for heavy nuclei gave ..cap alpha.. less than or equal to 2 x 10/sup -3/ at high (approx.99%) statistical confidence; preliminary calculations for detailed balance with /sup 24/Mg(..cap alpha..,p)/sup 27/Al and its inverse gives ..cap alpha.. less than or equal to 4 x 10/sup -3/ at the same high confidence, but less than or equal to0.2 x 10/sup -3/ at 80% confidence. Suggestions are made about experiments which should yield sharper bounds. 28 refs., 1 tab.
