Limits of Time-Reversal Violating Interaction from Compound Nuclear Experiments

Original · EN

Mean square matrix elements of the time reversal invariance violating (TRIV) interaction between the compound nuclear states are calculated within the statistical model, using the explicit form of the TRIV interaction via the ρ-meson exchange. From the comparison of the calculated values with the data known for p+ ²⁷Al ²⁴Mg + α reaction, and for γ-correlation measurements in ¹¹³Cd(n,γ)¹¹⁴Cd process, the bounds on the TRIV constant are obtained gρ 1.8 × 10⁻² and gρ 1.1 × 10⁻². The sensitivity of the recently proposed detailed balance test experiments on isolated resonances in ³²S to the value of gρ is shown to be as high as to reach values gρ 10⁻⁴.
