Evidence for the Natural Radioactivity of Indium [PDF]
Nature, 1951 A CONSIDERATION of the energetics of radioactive decay shows that two isotopes of the same mass number but neighbouring atomic number cannot both be stable if the rest mass of the neutrino is zero. A number of such neighbouring isobaric pairs exists in Nature; in some cases the expected radioactivity has been found in one member of the pair, with a ...
