High-resolution measurement of the time-modulated orbital electron capture and of the $β^+$ decay of hydrogen-like ${}^{142}$Pm${}^{60+}$ ions

Decays Collaboration, P. Kienle, F. Bosch +45

The periodic time modulations, found recently in the two-body orbital electron-capture (EC) decay of both, hydrogen-like ${}^{140}$Pr${}^{58+}$ and ${}^{142}$Pm${}^{60+}$ ions, with period…
