ABSTRACT A nuclear structure model of “ring plus extra nucleon” is proposed. For nuclei larger than 4 He, protons (P) and neutrons (N) are basically bound alternatively to form a Z P + Z N ring. The ring folds with a “bond angle” of 90° for every 3 continuous nucleons to make the nucleons packed densely. Extra N(‘s) can bind to ring-P with the same “bond angle” and “bond distance”. When 2 or more P’s are geometrically available, the extra N tends...
