Cyclotron radiation emission spectroscopy of electrons from tritium β decay and ^83mKr internal conversion

RADIOACTIVITY ⁸³Kr(IT); measured cyclotron radiation of emitted electron in magnetic field; deduced energy of internal conversion electrons (ce). ³H(β^-); measured cyclotron radiation of emitted beta electron in magnetic field; deduced β-decay end-point, neutrino upper mass-limit. Bayesian and frequentist fit analysis. Project 8, the cyclotron radiation emission spectroscopy (CRES) technique.
