In this work, we present the first spectroscopic measurements of conversion electrons originating from the decay of metastable gaseous 83m Kr with the Karlsruhe Tritium Neutrino (KATRIN) experiment. The obtained results represent one of the major commissioning milestones for the subsequent direct neutrino mass measurement with KATRIN. The successful campaign demonstrates the functionalities of the KATRIN beamline. Precise measurement of the narrow K-32, L 3 -32, and N 2,3 -32 conversion electron lines allowed to verify the eV-scale energy resolution of the KATRIN main spectrometer necessary for competitive measurement of the absolute neutrino mass scale.

气态83m Kr转换电子的高分辨率光谱和KATRIN实验
在这项工作中，我们用卡尔斯鲁厄Tri中微子（KATRIN）实验提出了源自亚稳态气态83m Kr衰变的转换电子的首次光谱测量。获得的结果代表了随后使用KATRIN进行直接中微子质量测量的主要调试里程碑之一。成功的战役展示了KATRIN光束线的功能。狭窄的K-32，L 3 -32和N 2,3 -32转换电子线的精确测量可以验证KATRIN主光谱仪的eV尺度能量分辨率，这是竞争性中微子质量尺度的测量所必需的。
