Summary

In part I of this paper, an isomorphism was shown to exist between the known nucleon eigenvalues and the symmetries of an anti-ferromagnetic face-centred cubic (FCC) lattice of protons and neutrons. Based upon the exact correspondence between nucleon states and positions in the FCC lattice, the properties of individual nuclei can be deduced with few additional assumptions or empirical input. Here, nuclear RMS radial values and binding energies of isotopes across the periodic chart have been determined. Nuclear « skin » parameters and the excited states of selected nuclei have also been calculated and demonstrate the realistic nature of FCC model predictions. Attenuation of the periodic chart atZ<110 is predicted and a brief comparison with other solid phase nuclear models is made.

Riassunto

Nella prima parte di questo lavoro è stato dimostrato un isomorfismo tra gli autovalori dei nucleoni e le simmetrie di un reticolo FCC di protoni e neutroni. Attraverso la corrispondenza degli stati nucleonici e le posizioni del reticolo FCC, le proprietà dei nuclei si possono dedurre con un minimo di assunzioni iniziali. In questa parte sono determinati i valori dei raggi (RMS), della energia di legame, i parametri di « skin » e gli stati eccitati di vari isotopi nella tavola periodica, che dimostrano la natura realistica delle predizioni del modello FCC. Si prevede una attenuazione della tavola periodica perZ<110 e si fa un breve confronto con altre teorie che si fondano su una fase solida del nucleo.
