标题： Limits of Time-Reversal Violating Interaction from Compound Nuclear Experiments

摘要： 均方矩阵元的时光反演不变性破坏（TRIV）相互作用在复合核态之间的计算是在统计模型中进行的，使用了通过$\rho$介子交换的TRIV相互作用的显式形式。从计算值与已知的$p+ ^{27}Al \Leftrightarrow ^{24}Mg + \alpha$反应数据以及$\gamma$相关测量在$^{113}Cd(n,\gamma)^{114}Cd$过程中的比较，得到了TRIV常数的限制${\bar g}_{\rho} \alt 1.8 \times 10^{-2}$和${\bar g}_{\rho} \alt 1.1 \times 10^{-2}$。 The sensitivity of the recently proposed detailed balance test experiments on isolated resonances in $^{32}S$ to the value of ${\bar g}_{\rho}$ is shown to be as high as to reach values ${\bar g}_{\rho} \sim 10^{-4}$. 显示英文摘要

摘要： 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 $\rho$-meson exchange. From the comparison of the calculated values with the data known for $p+ ^{27}Al \Leftrightarrow ^{24}Mg + \alpha$ reaction, and for $\gamma$-correlation measurements in $^{113}Cd(n,\gamma)^{114}Cd$ process, the bounds on the TRIV constant are obtained ${\bar g}_{\rho} \alt 1.8 \times 10^{-2}$ and ${\bar g}_{\rho} \alt 1.1 \times 10^{-2}$. The sensitivity of the recently proposed detailed balance test experiments on isolated resonances in $^{32}S$ to the value of ${\bar g}_{\rho}$ is shown to be as high as to reach values ${\bar g}_{\rho} \sim 10^{-4}$.
