Ivanov, A. N., Kryshen, E. L., Pitschmann, M., & Kienle, P. (2008). Time Modulation of the β+ -Decay Rate of H-Like 140Pr58+ Ions. Physical Review Letters, 101(182501). https://doi.org/10.1103/physrevlett.101.182501
Recent experimental data at GSI on the rates o 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.
