Generation of a directed mono-energetic neutrino beam and measurement of the neutrino mass

摘要

We study generation of a directional mono-energetic neutrino beam in electron capture beta-decay and analyze the recoil force exerted by neutrinos. We consider the influence of the neutrino rest mass on the recoil force and discuss the opportunity for neutrino mass measurement using an atomic force microscopy (AFM). We compute the enhancement of the signal-to-noise ratio due to signal accumulation (averaging), find the optimal time for signal accumulation and formulate conditions for measurement of neutrino mass with AFM.
