If any other nucleon is at a distance more
than the range of the nuclear force from the particular nucleon it will
have no influence on the binding energy of the nucleon under
consideration If a nucleon can have a maximum of p neighbours
within the range of nuclear force, its binding energy would be
proportional to p Let the binding energy of the nucleus be pk, where
k is a constant having the dimensions of energy If we increase A by
adding nucleons they will not change the binding energy of a nucleon
