摘要：亚稳稀有气体（Rg*）的MJ态选择是通过以下方法实现的： 由永久磁铁组成的磁性六极。磁六极的性能进行了检查，通过表征的速度分布和空间轮廓的状态选择Rg* 光束。使用位置分辨飞行时间进行表征 分析和弹道仿真。由于聚焦效应，磁六极将束流强度增强了至少一个数量级。此外，磁六极被发现作为一个很好的速度选择器。
Abstract.The MJ-state selection of the metastable rare-gas (Rg*) was achieved by a magnetic hexapole that is composed of permanent magnets. The performance of the magnetic hexapole was examined by characterizing the velocity distribution and the spatial profile of the state selected Rg* beam. The characterization was carried out using position resolved time-of-flight analysis and its trajectory simulation. The magnetic hexapole enhanced the beam intensity at least one order of magnitude owing to the focusing effect. In addition, the magnetic hexapole was found to act as a good velocity selector.
