The structure of the atomic nuclei, i.e. how protons and neutrons arrange themselves and how they interact among each other to form complex nuclei, has a decisive impact on everyday life, from the very existence of carbon-based life on Earth to critical nuclear physics applications such as carbon dating. Our understanding of nuclear structure is still elusive and relies on sophisticated experiments that deliver critical observables of atomic nuclei. For example, our experiments use particle accelerators that collide nuclei travelling at up to 50% the speed of light on stationary material to induce nuclear reactions. Typically, fewer than one in a million reactions will create the nucleus under study and the states of interest live, typically for less than a billionth of a second. To detect such rare events and measure the properties we are after, we need to develop very sensitive instruments. This project supports the development of one of the most sensitive "microscopes", the AGATA spectrometer, for gamma rays that are emitted during the accelerator-induced nuclear reactions. These gamma rays carry critical information about what happened during the (violent) nuclear reaction. By studying the energy and direction of the gamma rays, we can extract the properties of the atomic nuclei that were involved in the collisions. Our results will help address critical questions in modern nuclear science. AGATA constitutes a dramatic advance in gamma-ray detection that has wide ranging applications in medical imaging, astrophysics, nuclear safeguards and radioactive-waste monitoring, as well as introducing new detection capability for nuclear-structure studies. Indeed, the instrumentation and technical advances driven by this work and the knowledge gained by those involved will be important in a wide range of applications, such as in medicine and industry. For example, in medical imaging, reconstruction of the gamma-ray energies and determination of their direction will result in vastly improved images. Another beneficiary will be in nuclear safeguards where one of the big problems is the identification of the range of isotopes in waste and the determination of their quantities.

原子核的结构，即质子和中子如何安排自己以及它们之间的相互作用如何形成复杂的核，对日常生活具有决定性的影响，从地球上的基于碳的生命到关键的核物理应用，例如碳年代的核心物理学。我们对核结构的理解仍然难以捉摸，并且依赖于提供原子核的关键可观察物的复杂实验。例如，我们的实验使用粒子加速器，该加速器以固定材料上的光速高达50％的核心碰撞核，以诱导核反应。通常，只有不到一百万个反应中的不到一个将创建正在研究的核，而感兴趣的状态通常不到十亿秒。为了检测这些罕见事件并测量我们所追求的属性，我们需要开发非常敏感的仪器。 该项目支持最敏感的“显微镜”之一，即Agata光谱仪，用于在加速器诱导的核反应过程中发出的伽马射线。这些伽玛射线具有有关（暴力）核反应中发生的事情的关键信息。通过研究伽马射线的能量和方向，我们可以提取参与碰撞的原子核的特性。我们的结果将有助于解决现代核科学中的关键问题。 AGATA在伽马射线检测中构成了巨大的进步，该检测在医学成像，天体物理学，核保障措施和放射性废物监测中具有广泛的应用，并引入了核结构研究的新检测能力。的确，这项工作和相关人员所获得的知识所驱动的仪器和技术进步将在医学和工业等广泛的应用中很重要。例如，在医学成像中，伽玛射线能量的重建以及确定其方向将导致图像大大改善。另一个受益人将是核保障措施，其中最大的问题之一是识别废物中的同位素范围及其数量的确定。
