Light Scattering Phenomena in Atomic Systems

将进行一系列光散射的实验研究。 在较低的原子密度，或从原子共振较大的失谐，散射截面的偏振和频率依赖性将被用来提取数据的偶极跃迁矩阵元素的基础和激发能级的原子的过渡。 以这种方式测量的过渡矩阵元素作为复杂的原子结构计算的基准，它们提供的数据有助于解释原子宇称破坏实验。 在高原子密度下，多重光散射占主导地位，并且散射在宏观上很强。 对这些多重散射效应的研究也是该项目的一部分。

A series of experimental investigations of light scattering will be undertaken. At lower atomic density, or larger detunings from atomic resonance, the polarization and frequency dependence of the scattering cross section will be used to extract data on the dipole transition matrix elements for transitions out of the ground and excited levels of the atoms. Transition matrix elements measured in this way serve as benchmarks for sophisticated atomic structure calculations, and they provide data useful to interpretation of atomic parity violation experiments. At high atomic density, multiple light scattering dominates, and the scattering is macroscopically strong. Investigation of these multiple scattering effects also forms part of the project.
