类氢离子弱衰变中的反常现象
Anomalies in weak decays of H-like ions
摘要:
我们研究了不稳定系统衰减律中振荡的出现。我们特别讨论了在类氢离子的电子俘获衰变中出现的所谓GSI异常的情况,并证明了这种振荡不能用中微子振荡来解释。然后,我们讨论如何这样的异常可能是密切相关的不稳定系统的衰变规律的情况下,他们的光谱函数偏离布赖特-维格纳形状。
英文摘要:
We investigate the emergence of oscillations in the decay law of unstable systems. We discuss in particular the case of the so-called GSI anomaly seen in the electron capture decays of H-like ions and prove that such oscillations cannot be explained by neutrino oscillations. We then discuss how such anomalies could be intimately related to the decay law of unstable systems in the case in which their spectral function deviates from a Breit-Wigner shape.
