The Structure of the Nucleus and its Total Moment of Momentum

The known values of the nuclear moment are classified in four divisions according to even and odd nuclear number and even and odd atomic number. All of the 31 cases are consistent with, and 12 cases in two divisions definitely support the hypotheses that: 1st, The electrons in the nucleus have no spin; 2nd, The protons have a spin of 1/2 in units of $\frac{h}{2\pi }$. These hypotheses are applied to the building up of the nuclei of equivalent protons, and the results indicate that: (1). There is an analogy between the construction of the nucleus of equivalent protons and the construction of the extranuclear portion of the atom of equivalent electrons. (2). Five quantum numbers are associated with the proton, corresponding to the five quantum numbers of the electron. (3). The rules of Pauli and Hund may be applied to the protons. (4). ($\mathrm{ii}$) coupling predominates for the protons. (5). The nuclear moment is to be identified with the inner protonic quantum number of the normal nuclear state. (6). The nuclear moment $I$ is in general the smallest $I$ of the lowest $I$-group. (7). The order of filling of the protonic subgroups is somewhat similar, especially for small nuclear numbers, to the order of filling of the electronic subgroups of an atom.
