Electron Capture in 163Ho and Overlap plus Exchange Corrections and the Neutrino Mass

Understand

Holmium 163 offers perhaps the best chance to determine the neutrino mass by electron capture.

• This contribution treats the electron capture in 163 Holmium completely relativistic for the overlap and exchange corrections and the description of the bolometer Spectrum.
• The theoretical expressions are derived assuming single Slater determinants for the initial Ho and the final Dy Atoms.
• Electron capture is proportional to the probability to find the captured electron in the parent atom at the nucleus.
