Storage rings have been employed over three decades in various kinds of nuclear and
atomic physics experiments with highly charged ions. Storage ring operation and precision …

Beta decay of highly charged ions has attracted much attention in recent years. An obvious
motivation for this research is that stellar nucleosynthesis proceeds at high temperatures …

The theory underlying neutrino oscillations has been described at length in the literature.
The neutrino state produced by a weak decay is usually portrayed as a linear superposition …

Determining the electron neutrino mass by electron capture in 163 Ho relies on an accurate
understanding of the differential electron capture nuclear decay rate as a function of the …

An experiment addressing electron capture (EC) decay of hydrogen-like Pm 60+ 142 ions
has been conducted at the experimental storage ring (ESR) at GSI. The decay appears to be …

Several older and recent reports provided evidence for the oscillatory character of the
exponential decay law in radioactive decay and attempted to explain it with basic physics …

Highly charged radioactive ions can be stored for extended periods of time in storage rings
which allows for precision measurements of their decay modes. The straightforward …

In this article, I provide a pedagogical discussion of the GSI anomaly. Using two different
formulations, namely the intuitive quantum-field-theory language of the second quantized …

We study the deviations from the usual exponential decay law for quantum mechanical
systems. We show that simple and physically motivated deviations from the Breit-Wigner …

The electron-capture decay of 180Re has been investigated to search for oscillations in the
decay probability as reported from a recent measurement at GSI, Darmstadt. The production …
