by K. Fuchs
By means of purely qualitative arguments which do not depend
on any particular model the general scheme of stable nuclei and
the isotopic breadth of nuclei with odd charge number has been
The breadth of the isobaric region can only be obtained if
the numerical values of certain energies are known. Though these
can be estimated only very roughly, the values for the breadth of
the isobaric region obtained in this way-are in good agreement with
the experimental values, The increase in the breadth of the
isobaric region from light nuclei to heavier nuclei can be explained,
but no plausible explanation has been found for the fact that for
the heaviest nuclei it decreases again,
