Abstract
By means of a high intensity mass spectrometer we have separated the isotopes of rubidium. Measurements of the radioactivity of the isotopic samples indicate that ${\mathrm{Rb}}^{87}$ is radioactive and that there is no other isotope with an appreciable activity compared to ${\mathrm{Rb}}^{87}$.
