Abstract

This paper is addressed to the proof of the important role of measuring apparatus, i.e. the measuring process, in the formation of necessary and sufficient conditions for the explanation of a time modulation of K-shell electron capture (EC) decay rates of hydrogen-like (H-like) heavy ions (or the GSI oscillations) as the interference of neutrino mass-eigenstates of the electron neutrino constituents. For our analysis we use a toy-model, which has been recently proposed by Peshkin arXiv: 1403.4292 [nucl-th] for a verification of the mechanism of the GSI oscillations as the interference of neutrino mass-eigenstates by Ivanov and Kienle Phys. Rev. Lett. 103, 062502 (2009).
