~(180)Re和~(142)Pm原子K壳层电子俘获衰变速率

Rates of K-shell Electron Capture Decays of 180Re and 142Pm Atoms

A. N. Ivanov, P. Kienle, M. Pitschmann

摘要:

我们提出了一个理论分析的实验数据的时间行为K壳层电子捕获(EC)原子180 Re和142 Pm在固体靶中,最近获得的Faestermann等人。B 672,227(2009)和Vetter等人,Phys. Lett. B 670,149(2008)。我们发现,在这些数据中的时间调制的情况下,排除了“GSI振荡”的解释(于。A. Litvinov等人,Phys. Lett. B 664,162(2008))。

英文摘要:

We propose a theoretical analysis of the experimental data on the time behaviour K-shell electron capture (EC) decays of atoms 180Re and 142Pm in solid targets, obtained recently by Faestermann et al. Phys. Lett. B 672, 227 (2009) and Vetter et al., Phys. Lett. B 670, 149 (2008). We show that the absence of the time modulation in these data rules out the explanation of the "GSI Oscillations" (Yu. A. Litvinov et al., Phys. Lett. B 664, 162 (2008)) by means of two closely spaced ground mass-eigenstates of mother nuclei.
