Abstract

New values for the ‘packing fraction’ of atoms of titanium (mass 48), chromium (mass 52), nickel (mass 58) and bromine (mass 79 and 81) are given by Dr. F. W. Aston, as calculated from mass spectrographic measurements on doublets (electrically charged atoms and groups of atoms having the same mass/charge ratio). A knowledge of the packing fraction is necessary in calculating energy changes involved in atomic transmutations.
