Experiments with Solar and Atmospheric Neutrinos: Evidence for Neutrino Masses and Lepton Mixing
Dr. Stefan Schoenert (Max-Planck-Institut für Kernphysik)

Data from experiments both with solar and atomospheric neutrinos strongly indicate that neutrinos oscillate and therefore do have non-zero restmasses. Recent results of the Sudburry Neutrino Observatory have strengthened the case. I shall review the experimental situation, open questions and future projects.
