Abstract: The theory underlying neutrino oscillations has been described at length inthe literature. The neutrino state produced by a weak decay is usuallyportrayed as a linear superposition of mass eigenstates with, variously, equalenergies or equal momenta. We point out that such a description is incomplete,that in fact, the neutrino is entangled with the other particle or particlesemerging from the decay. We offer an analysis of oscillation phenomenainvolving neutrinos applying equally well to neutral mesons that takesentanglement into account. Thereby we present a theoretically sound proof ofthe universal validity of the oscillation formulae ordinarily used. In sodoing, we show that the departures from exponential decay reported by the GSIexperiment cannot be attributed to neutrino mixing. Furthermore, we demonstratethat the `Mossbauer- neutrino oscillation experiment proposed by Raghavan,while technically challenging, is correctly and unambiguously describable bymeans of the usual oscillation formalae.
