Contribution

It introduces a novel method to control decay rates via multiphoton transitions, potentially explaining the GSI anomaly.

Findings

Decay rate oscillates with frequency up to 0.1 Hz

Experimental setup proposed for ion storage in a Penning trap

Provides a possible explanation for the GSI anomaly

Abstract

The multiphoton resonance transitions between ground hyperfine states are used for the time modulation of the electron capture decay of hydrogen like ions with the Gamow-Teller transition $1^+\to 0^+$. The proposed mechanism offers a time oscillating decay with the frequency up to 0.1 Hz. The experiment to observe the modulation is proposed for ions stored in a Penning trap. An attempt to understand the GSI anomaly with multiple photon transitions is made.
