论文摘要
快速原子束的界线激光光谱已被确定为用含有短寿命核的原子进行精确实验的主要工具之一。尽管高度敏感，但这些技术的光谱分辨率通常仅限于几个MHz。在这里，我们研究了瞬时干扰现象的使用来潜在地改善实验分辨率。先前尝试使用快速梁实施拉姆西型测量值的尝试受到对观察到的线形状的了解的限制。通过使用简单的模型，我们提供了对先前观察到的线形形状的令人满意的描述，并提出了替代实验方案，以改善快速离子梁实验中的分辨率。
Collinear laser spectroscopy of fast atomic beams has been established as one of the main tools to perform precision experiments with atoms containing short-lived nuclei. Although highly sensitive, the spectral resolution of these techniques is typically limited to several MHz. Here, we study the use of transient interference phenomena to potentially improve the experimental resolution. Previous attempts to implement Ramsey-type measurements with fast beams were limited by the lack of understanding of the observed line shapes. By using a simple model, we provide a satisfactory description of the previously observed line shapes, and propose alternative experimental schemes to improve the resolution in fast ion-beam experiments.
