Long term stability of the energy of conversion electrons emitted from solid 83Rb/83mKr source
摘要：
83 mKr衰变产生的单能转换电子为KATRIN中微子质量实验中氚β谱测量的能量刻度、能标监测和系统研究提供了独特的工具。为此，用两台电子能谱仪研究了固体~（83）Rb/~（83）mKr真空蒸发源衰变中7.5keV和17.8keV转换电子布居的能量长期稳定性。
英文摘要：
The mono-energetic conversion electrons from the decay of 83mKr represent a unique tool for the energy calibration, energy scale monitoring and systematic studies of the tritium beta spectrum measurement in the neutrino mass experiment KATRIN. For this reason, the long term stability of energy of the 7.5 keV and 17.8 keV conversion electrons populated in the decay of solid 83Rb/83mKr vacuum evaporated sources was examined by means of two electron spectrometers.
