We study the thermodynamic properties of a simple model for the possible
mechanism of attraction between like charged rod-like polyions inside a
polyelectrolyte solution. We consider two polyions in parallel planes, with Z
charges each, in a solution containing multivalent counterion of valence a. The
model is solved exactly for Z [ 13 for a general angle h between the rods and
