分析AGATA在相对论能量的束内射线光谱的能力。AGATA确定锗晶体中射线相互作用点位置的能力，为在发射核以超过光速一半的速度行进时获得高射线能量分辨率提供了关键因素。这是未来FAIR设施中SuperFRS光谱仪的外来核的典型速度，AGATA将作为高分辨率束内光谱项目HISPEC的一部分部署在那里。在这些条件下，使用AGATA不同的实验技术的讨论，包括分析不同的多普勒为基础的寿命测定方法。预计将在FAIR束射线光谱应用的关键反应机制的属性进行了讨论，沿着这些反应的方面，可以利用先进的能力的AGATA阵列。
An analysis of the capabilities of AGATA for in-beam-ray spectroscopy at relativistic energies is presented. AGATA’s ability to determine the position of-ray interaction points in the Germanium crystal provides the crucial ingredient for attaining high-ray energy resolution when the emitting nucleus is traveling at more than half the speed of light. This is the typical velocity of exotic nuclei exiting the SuperFRS spectrometer at the future FAIR facility, where AGATA will be deployed as part of the high-resolution in-beam spectroscopy project, HISPEC. A discussion of different experimental techniques using AGATA under these conditions is presented, including analysis of the different Doppler-based methods for lifetime determination. The properties of the key reaction mechanisms expected to be applied for in-beam-ray spectroscopy at FAIR are discussed, along with the aspects of those reactions that can be exploited by the advanced capabilities of the AGATA array.
