Gamma radioactivity of anomalous wells

Abstract: Gamma emission of nuclear energy scale ($\sim 3MeV$), caused by electron transitions in anomalous wells, is predicted to occur in acoustic experiments with solids. The anomalous well for electrons is formed by a local reduction of electromagnetic zero point energy in a vicinity of a nucleus which can be a lattice site of a solid [1]. The well width is $\sim 10^{-11}cm$ and the well depth is $\sim 3MeV$. An energy spectrum in anomalous wells is continuous and non-decaying. Unusual experimental results, on unexpected emission from lead of $\sim 1keV$ x-rays under acoustic pulses, are likely explained by formation of anomalous wells [2]. The experimentally observed $keV$ quanta are naturally supplemented by $MeV$ emission to be revealed. This conclusion is drawn on the basis of an exact solution within a model generic with quantum electrodynamics. An energy of emitted quanta (x-rays and gamma) comes from a reduction of electromagnetic zero point energy (energy from "nothing").
