Abstract
THE isotopic weight and ‘packing fraction’ of several atomic species have been determined by Dr. F. W. Aston with his new mass-spectrograph by comparison of doublets (atoms and groups of atoms having nearly the same mass/charge ratio). Dr. Aston gives revised figures for the relative abundance of various isotopes of cadmium, tin and lead. The existence of Fe 58 and Ni 64 is supported by the experiments of Gier and Zeeman, but evidence as to Ni 61 is still conflicting.
