  A contribution is presented to the application of fractal properties and
log-periodic corrections to the masses of several nuclei (isotopes or
isotones), and to the energy levels of some nuclei. The fractal parameters
$\alpha$ and $\lambda$ are not randomly distributed, but take a small number of
values, common also with the values extracted previously from fractal
distributions of quark, lepton, and hadronic masses. Several masses of still
unobserved nuclei are tentatively predicted.
