论文摘要
中微子质量实验Katrin使用来自核异构体$^{\ Mathrm {83m}} $ kr的32.2 KeV过渡的转换电子进行校准。将测得的能量与适当的文献值进行比较，可以独立评估能量量表，但是通过伽马光谱获得的某些文献值中的不确定性是一个限制因素。本文以Katrin能量量表的出色线性为基础，提出了一种新方法，用于确定$^{\ Mathrm {83M}} $ KR Transition Energies通过高精度电子光谱。值得注意的是，该方法利用了从$^{\ mathrm {83m}} $ kr的41.6 keV直接过渡中的转换电子，除了从32.2-Kev和9.4 kev transition的频繁级联的转换电子之外，除了转换电子外。通过实现此方法，Katrin可以比当前$^{\ Mathrm {83M}} $ KR Transition Energy文献值提供精度的精确顺序改进。
The neutrino mass experiment KATRIN uses conversion electrons from the 32.2 keV transition of the nuclear isomer $^{\mathrm{83m}}$Kr for calibration. Comparing the measured energies to the appropriate literature values allows for an independent evaluation of the energy scale, but the uncertainties in some of the literature values obtained by gamma spectroscopy are a limiting factor. Building upon the already excellent linearity of KATRIN's energy scale, this paper proposes a novel method for determining the $^{\mathrm{83m}}$Kr transition energies via high-precision electron spectroscopy. Notably, the method makes use of conversion electrons from the 41.6-keV direct transition of $^{\mathrm{83m}}$Kr to its ground state in addition to conversion electrons from the much more frequent cascade of a 32.2-keV and a 9.4-keV transition. By implementing this method, KATRIN may be able to deliver order-of-magnitude improvements in precision over current $^{\mathrm{83m}}$Kr transition energy literature values.
