This is a combined project in atomic photoionization and ion-molecule scattering. In the first part of the project the group will study the angular momentum partitioning of the electronic components of the Ar atom when it is photoionized by circularly polarized synchrotron radiation. By determining the spin components of the residual excited ion and free electron, the group will be able to quantify the importance of relativistic, spin-orbit interactions in the photo process. In the second part of the project the group will study the highly correlated motion of three massive Coulomb interacting particles when the total energy of the three particles is a few eV above the continuum. The response of the three-body motion to a change in mass dependent variables of momentum and energy will provide information regarding the important parameter of energy sharing in three body systems.

这是一个结合原子光电离和离子分子散射的项目。 在该项目的第一部分，该小组将研究Ar原子被圆偏振同步辐射光电离时电子成分的角动量分配。 通过确定剩余激发离子和自由电子的自旋分量，该小组将能够量化相对论性自旋轨道相互作用在光过程中的重要性。 在该项目的第二部分中，该小组将研究当三个大质量库仑相互作用粒子的总能量比连续统高几eV时，这三个粒子的高度相关运动。 三体运动对动量和能量的质量相关变量的变化的响应将提供关于三体系统中能量共享的重要参数的信息。
