Research on Neutrino Oscillation-Induced Radioactive Decay
Guowen Zhang, Mengke Zhang
Abstract: Usually, the decay rate of radioactive elements is considered to be a constant, but in recent years, studies on the possible influence of the solar neutrino flux on the decay rate of radioactive elements have attracted attention and controversy. In this paper, we investigate the material effects of neutrino oscillations and the influence of the resulting effective potential field on radioactive nuclei based on the theory of neutrino oscillations and the model of the decay of radioactive elements. The results show that matter effect on neutrino oscillations (MSW) is a resonance of neutrinos with atoms in medium. This resonance is different from the reaction of collisions between individual particles and is a collective behavior between neutrinos and atoms in medium linked by a potential field. This resonance, while strongly affecting neutrino oscillations and leading to enhanced neutrino flavor conversion probability, also affects atoms in medium, exciting unstable radioactive nuclei in them and increasing their decay probability. Furthermore, we show that even if neutrinos cannot form resonances (MSW) with atoms in medium (including radioactive atoms therein), neutrino oscillations can have an effect on the decay rate of radioactive atoms as long as they are capable of forming a stable periodic effective potential field. Finally, we explain the fluctuations in the measured decay rates of radioactive elements and discuss the significance of neutrino oscillation-induced radioactive decay.
