Abstract
UNDER the above title, Mr. James H. Bartlett, jr.,1 has indicated a simple regularity in the known nuclei of low atomic number, without being aware of the fact that I pointed out these regularities about a year ago.2 He states: “The purpose of this note is to point out regularities for elements of low mass, and to suggest a possible building-up principle for such elements”. The discussion of the next two paragraphs has been completely covered in the paper referred to above. The diagrams were made on the basis of building nuclei from protons and electrons, but the text pointed out that the building could be made from protons and neutrons very simply. This regularity was one fact which induced Dr. F. G. Brickwedde, Dr. G. M. Murphy, and me 3 to look for an isotope of hydrogen of mass 2, as stated in our paper. Moreover, in this paper we directed attention to this simple regularity among nuclei of low mass, and reproduced the proton-electron plot on page 14. It is only necessary to interpret each diagonal unit as the addition of a neutron and each vertical unit as the addition of a proton to secure the regularity pointed out by Mr. Bartlett.
