AI 中文摘要
氚的束缚态β衰变是弱相互作用标准理论所预言的过程，即末态电子在产生的³He原子的束缚原子态中产生而非自由飞出，但至今未被观测到。我们研究通过探测此过程产生的中性³He激发原子态辐射衰变的光子来进行实验观测的可能性。我们还基于通过发射光子线的多普勒展宽精确测定产生的³He原子速度，提出了一种直接测量中微子质量和寻找惰性中微子的新方法。
英文摘要
Bound-state $β$-decay of tritium, the process, in which the final-state electron is created in a bound atomic state of the produced ${\rm ^3He}$ atom instead of freely flying away, is predicted by the standard theory of weak interactions but has not been observed so far. We study the possibility of its experimental observation through the detection of photons from radiative decay of the excited atomic states of neutral ${\rm ^3He}$ populated by this process. We also propose a novel approach to direct neutrino mass measurement and sterile neutrino search based on accurate determination of the speed of the produced ${\rm ^3He}$ atoms through Doppler broadening of the emitted photon lines.
