论文摘要
可以通过核衰减链和两个产生的高能$γ$ S的转换为电子 - 质体对，研究了“ X17拼图”是否可以解释。发现相应的运动学完全符合实验结果。此过程的转换率也很合理。然而，在已建立的核模型中不利假设的核链反应，也没有对信号的同胞结构的解释。因此，必须得出结论，本文研究的过程并不能完全令人满意地解释“ X17拼图”。
It is investigated whether the "X17 puzzle" might be explained by a nuclear decay chain and a conversion of the two resulting highly energetic $γ$s into an electron-positron pair. It is found that the corresponding kinematics fits perfectly to the experimental result. Also the conversion rates of this process are reasonable. However, the assumed nuclear chain reaction is not favored in the established nuclear models and no explanation for the isospin structure of the signal can be given. Thus, it has to be concluded that the process studied in this paper does not give a completely satisfying explanation of the "X17 puzzle".
