Development of threshold photoelectron-photoion coincidence spectroscopy at the CRIS experiment

我的博士项目的主要目标将是通过测量外来核的超精细结构来研究它们的核结构。这将使用欧洲核子研究中心的共线共振电离光谱(CRIS)实验进行，该实验结合了共线激光光谱的高分辨率和离子探测的高效率。所讨论的核，包括富中子的氧和氟同位素，以及贫中子的锡同位素，位于核存在的边缘，使用CRIS技术进行研究将提供适用于测试现代核模型的无假设测量。例如23o，这是很有意思的，因为它的测量将有力地检验包括三体核力在内的有效场理论。

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.
