Comment on "New method for studying neutrino mixing and mass differences"

TL;DR

This paper critically examines a proposed explanation for observed decay rate oscillations in Pr ions, demonstrating that interference effects cannot account for the phenomenon, thus challenging prior interpretations.

Contribution

It provides a theoretical refutation of the interference hypothesis for decay oscillations in Pr ions, clarifying the underlying physics.

Findings

Interference between different momenta cannot cause decay rate oscillations.

The observed oscillations are not due to quantum interference effects.

The paper refutes a specific proposed mechanism for neutrino-related decay phenomena.

Abstract

It has been suggested that the temporal oscillations in the rate of decay of Pr ions reported in the GSI K-capture experiment arise from interference between different values of the momentum of the Pr ions. It is shown here that any such interference cannot contribute to the decay rate of those ions.
