A New Technique for the Direct Measurement of the Electron Anti-Neutrino Mass

Recently Raghavan [1] has proposed to measure the gravitational red shift of the electron neutrino and the neutrino mixing angle θ13 using a tritium-metal matrix source and He-metal matrix target. The line width of the tritium source and capture cross-section in He are enhanced by a combined factor of ∼ 10 via the Mossbauer effect. We show how this technique can be used to directly measure the mass of the electron neutrino PACS nos. 13.15+g, 14.60.Pq, 23.40.-s.
