本文以铋-209为基准,理论研究了μ子与高磁矩原子核弹性散射中的极化动力学,发现核结构修正显著影响微分截面和极化观测量,并表明测量散射μ子极化可灵敏探测核电荷半径和磁偶极矩。
AI 中文摘要
我们提出了一个关于μ子和反μ子被高磁矩原子核弹性散射时极化动力学的理论研究,以${}_{83}^{209}$Bi为基准。该分析追踪了(反)μ子极化的演化及其向原子核的转移,强调了核结构修正。这些修正显著改变了微分截面和极化观测量。我们的结果表明,测量散射μ子的极化可作为核电荷半径和磁偶极矩的灵敏探针。
英文摘要
We present a theoretical study of polarization dynamics in the elastic scattering of muons and antimuons by high-magnetic-moment atomic nuclei, using ${}_{83}^{209}$Bi as a benchmark. The analysis tracks the evolution of (anti)muon polarization and its transfer to the nucleus, emphasizing nuclear-structure corrections. These corrections significantly alter both the differential cross sections and the polarization observables. Our results demonstrate that measuring scattered muon polarization serves as a sensitive probe for nuclear charge radii and magnetic dipole moments.
