 Existence of many-particle bound states in spite of a
 pair-interaction with positive scattering length
(24K, LATeX 2e)

ABSTRACT.  Examples of bound states are presented, for a system of three identical 
particles as well as for a system of particles on a lattice. The 
particles may be bosons as well as fermions. The interaction between them
is given by a pair-potential, which does not allow two-particle bound
states, has positive scattering length and is not too different from
realistic interatomic potentials.
