Mass measurements for neutrino physics
Dr. Szilard Nagy (Institut für Physik - MPI für Kernphysik, Heidelberg)


The rest mass and the Majoranna or Dirac nature of neutrinos are still open questions in physics. By searching for neutrinoless double-beta decays or neutrinoless double-electron-capture transitions and studying beta decays the true identity of neutrinos is expected to be uncovered. In these transitions the masses of the mother and daughter atoms play a key role therefore their precise knowledge is important.
Advances in Penning trap mass spectrometry made high-precision mass determinations possible, reviving the interest and triggering new theoretical calculations in this field.
The mass measurement techniques with Penning traps will be briefly introduced.
New results relevant for neutrino physics will be presented focusing on recent achievements at the TRIGA-TRAP experiment.
