Phys. Rev. Lett. 103, 062502 (2009) [4 pages]Time Modulation of the K-Shell Electron Capture Decay Rates of H-like Heavy Ions at GSI ExperimentsReceived 9 April 2009; published 6 August 2009 According to experimental data at GSI, the rates of the number of daughter ions, produced by the nuclear K shell electron capture decays of the H-like heavy ions with one electron in the K shell, such as 140Pr58+, 142Pm60+, and 122I52+, are modulated in time with periods TEC of the order of a few seconds, obeying an A scaling TEC=A/20 s, where A is the mass number of the mother nuclei, and with amplitudes adEC∼0.21. We show that these data can be explained in terms of the interference of two massive neutrino mass eigenstates. The appearance of the interference term is due to overlap of massive neutrino mass eigenstate energies and of the wave functions of the daughter ions in two-body decay channels, caused by the energy and momentum uncertainties introduced by time differential detection of the daughter ions in GSI experiments. © 2009 The American Physical Society URL:
