Query: Remarkable long-range-systematic in the binding energies of alpha-nuclei
  II   In this letter I present further data that show the remarkable evidence for
the existence of an alpha-cluster stucture in the ground states of even-even
N=Z nuclei. Such a remarkable systematic was observed 20 years ago for these
nuclei at A<= 72 and is extended here up to A=100.
