The primary aim of my PhD project will be the investigation of the nuclear structure of exotic nuclei through the measurement of their hyperfine structure. This will be performed using the Collinear Resonance Ionisation Spectroscopy (CRIS) experiment at CERN, which combines the high resolution of collinear laser spectroscopy with the high efficiency of ion detection. The nuclei in question, which include neutron-rich isotopes of oxygen and fluorine, and neutron-deficient isotopes of tin, lie at the edges of nuclear existence and investigating them using the CRIS technique will provide assumption-free measurements suitable for testing modern nuclear models. For example 23O, this is of interest as its measurement would robustly test effective field theories that include three body nuclear forces.

我的博士项目的主要目标是通过测量奇异核的超精细结构来研究它们的核结构。这将使用CERN的共线共振电离光谱（CRIS）实验进行，该实验将共线激光光谱的高分辨率与离子检测的高效率相结合。所讨论的原子核包括氧和氟的富中子同位素以及锡的缺中子同位素，它们处于核存在的边缘，使用CRIS技术对其进行研究将提供适合于测试现代核模型的无反射测量。例如23O，这是令人感兴趣的，因为它的测量将有力地测试包括三体核力的有效场论。
