Abstract
Within the framework of an extensive programme devoted to the search for alternative candidates for the neutrino mass determination, the atomic mass difference between Pb-202 and Tl-202 has been measured with the Penning trap mass spectrometer ISOLTRAP at the ISOLDE facility at CERN. The obtained value keV is three times more precise than the AME2012 value. While it will probably not lead to a replacement of Ho-163 in modern experiments on the determination of the electron-neutrino mass, the electron capture in Pb-202 would however allow a determination of the electron-neutrino mass on the few-eV level using a cryogenic micro-calorimeter.
