- "The most convenient and informative expression for the divergences of an atom from the whole number rule is the actual divergence divided by its mass number. This is the mean gain or loss per proton when the nuclear packing is changed from that of oxygen to that of the atom in question. It will be called the packing fraction of the atom and expressed in parts per 10,000."

- "In 1927 Aston published his measurements of the deviations of the nuclidic weights from integers in the form of a packing fraction curve that reflects the variation of the binding energy per nucleon with the number A of nucleons in the various nuclides."
