It is shown that the rule of Niggli and Sonder can be interpreted as a structure effect when the isotopes are divided into groups and families. On the basis of the family with m=4 n it is demonstrated that the phenomena can be understood on the hypothesis that the nuclei of this family are composed only of N P- and N P-bodies. The latter incline to duplication, so that even numbers of N P-bodies, and especially the number 10, lend the nucleus increased stability, as can easily be proved statistically.
