论文摘要
需要评估在实验室实验中使用中子镜的可行性，以搜索中子抗抗酸的振荡。我们分析了对这些值的现有实验和理论约束，重点是低$ a $ nuclei，并使用结果为中子/抗神经指南提出了材料，并评估了估计中子 - 静脉振荡时间的系统不确定性。例如，我们讨论了针对欧洲散布来源提出的未来中子 - 抗抗振荡实验的场景。我们还建议将来的实验，可以更好地确定抗神经核核散射长度的值。
The values of the antineutron-nucleus scattering lengths, and in particular their imaginary parts, are needed to evaluate the feasibility of using neutron mirrors in laboratory experiments to search for neutron-antineutron oscillations. We analyze existing experimental and theoretical constraints on these values with emphasis on low $A$ nuclei and use the results to suggest materials for the neutron/antineutron guide and to evaluate the systematic uncertainties in estimating the neutron-antineutron oscillation time. As an example we discuss a scenario for a future neutron-antineutron oscillation experiment proposed for the European Spallation Source. We also suggest future experiments which can provide a better determination of the values of antineutron-nuclei scattering lengths.
