There is More than One Kind of Neutrino (1962)
Siegmund Brandt · 1992
Abstract In Episode 79 we mentioned that the muon decays into an electron and two neutrinos and that this fact was ascertained, in particular, on the basis of measurements which Steinberger performed for his thesis and published in 1949. A dozen years later he was the senior scientist in a group demonstrating that these two neutrinos are of different nature.
