Resonant neutrino activation and neutrino oscillations

摘要: Low Q value weak nuclear decays are considered which have two body final states (electron captures and bound state beta decays, BSD). This permits an analogy with the Mossbauer effect, where emitted (anti) neutrinos will resonantly activate daughter nuclei in a suitable absorber. Candidates for such process examined relevant solid host problems discussed. We point out that resonant line widths as large narrowest observed spectroscopy suffice to greatly extend sensitivity of ν [disappearance] oscillation experiments.
