关于“对GSI实验中类氢重离子K壳层电子俘获衰变率的时间调制”一文的答复

Reply on "Comments on 'Time modulation of the K-shell electron capture decay rates of H-like heavy ions at GSI experiments'"

A. N. Ivanov, P. Kienle

摘要:

根据GSI的实验数据,由类H的140 Pr 58+、142 Pm 60+和122 I52+离子的核K壳层电子捕获(EC)衰变产生的子离子的数量的速率在时间上以几秒量级的周期T_{EC}进行调制,服从A标度T_{EC} = A/20 s,其中A是母核的质量数,并且具有振幅a^{EC}_d ~ 0.21。反过来,正电子衰变模式的H-样142 Pm 60+离子表现出没有时间调制的衰变率。如在Phys. Rev. Lett中所示。103,062502(2009)和Phys. Rev. Lett. 101,182501(2008),这些数据可以通过两个中微子质量本征态的干涉来解释。在这封信中,我们给我们的论文的评论的答复物理。103,062502(2009)由V. Flambaum(arXiv:0908.2039 [nucl-th])。

英文摘要:

According to experimental data at GSI, the rates of the number of daughter ions, produced by the nuclear K-shell electron capture (EC) decays of the H-like 140Pr58+, 142Pm60+ and 122I52+ ions, are modulated in time with periods T_{EC} of the order of a few seconds, obeying an A-scaling T_{EC} = A/20 s, where A is the mass number of the mother nuclei, and with amplitudes a^{EC}_d ~ 0.21. In turn, the positron decay mode of the H-like 142Pm60+ ions showed no time modulation of the decay rates. As has been shown in Phys. Rev. Lett. 103, 062502 (2009) and Phys. Rev. Lett. 101, 182501 (2008), these data can be explained by the interference of two neutrino mass-eigenstates. In this letter we give a reply on the comments on our paper Phys. Rev. Lett. 103, 062502 (2009) by V. Flambaum (arXiv: 0908.2039 [nucl-th]).
