Measuring the electron neutrino mass using the electron capture decay of 163Ho
Joel Ullom, Daniel Schmidt, Simon Bandler +14
While the mass differences between neutrino mass states are known, their absolute masses and mass hierarchy have not yet been determined. Determining the mass of neutrinos provides…
