DESCRIPTION:We consider a dilute stationary system of N particles uniforml
 y distributed in space and interacting pairwise according to a compactly s
 upported potential\, which is repellent at short distances and attractive 
 at moderate distances. We are interested in the large-N behaviour of the s
 ystem. We show that at a certain scale there are phase transitions in the 
 temperature parameter and describe the energy and ground states explicitly
  in terms of a variational problem. This is a joint work with Andrea Colle
 vecchio\, Wolfgang Koenig and Peter Moerters.
