μ子催化的“飞行中”d-t聚变中的α-μ子粘附和混沌
Alpha-muon sticking and chaos in muon-catalysed "in flight" d-t fusion
摘要：
本文在约束分子动力学模型的框架下讨论了μ子催化的“飞行中”d-t聚变中α-μ子的粘附系数。重点研究了μ子混沌动力学对粘附系数的影响。μ子的混沌运动不仅影响熔合截面，而且影响$μ-α$的粘附系数。由于隧穿区的减小，混沌系统相对于常规系统导致更大的增强。此外，它们给出的粘滞概率比规则事件的粘滞概率小。通过利用混沌动力学的特性，可以避免在$μ$ CF循环中丢失μ子。我们建议将所谓的“里德伯原子的微波电离“应用于目前的情况，这可能导致使用X射线增强再活化过程。
英文摘要：
We discuss the alpha-muon sticking coefficient in the muon-catalysed ``in flight" d-t fusion in the framework of the Constrained Molecular Dynamics model. Especially the influence of muonic chaotic dynamics on the sticking coefficient is brought into focus. The chaotic motion of the muon affects not only the fusion cross section but also the $μ-α$ sticking coefficient. Chaotic systems lead to larger enhancements with respect to regular systems because of the reduction of the tunneling region. Moreover they give smaller sticking probabilities than those of regular events. By utilizing a characteristic of the chaotic dynamics one can avoid losing the muon in the $μ$CF cycle. We propose the application of the so-called ``microwave ionization of a Rydberg atom" to the present case which could lead to the enhancement of the reactivation process by using X-rays.
