Phys. Rev. Lett. 101, 182501 (2008) [4 pages]Time Modulation of the β+-Decay Rate of H-Like 140Pr58+ IonsReceived 16 June 2008; published 29 October 2008 Recent experimental data at GSI on the rates of the number of daughter ions, produced by the nuclear K-shell electron capture (EC) decays of the H-like ions 140Pr58+ and 142Pm60+, suggest that they are modulated in time with periods TEC≃7 sec and amplitudes aEC≃0.20. Since it is known that these ions are unstable also under the nuclear positron (β+) decays, we study a possible time dependence of the nuclear β+-decay rate of the H-like 140Pr58+ ion. We show that the time dependence of the β+-decay rate of the H-like 140Pr58+ ion as well as any H-like heavy ions cannot be observed. © 2008 The American Physical Society URL:
