Solutions of polyelectrolyte are studied by small angle neutron scattering for c > 0.5 x 10-2 g. cm -3. The function S(q) is characterized by a small value of S'(q → 0) and one broad maximum for higher q's (10-2 < q < 2 x 10-1 Å-1) . The effect of polyion concentration and addition of salt are studied : the position of the maximum varies with polyion concentration and when salt is added to the solution, forward scattering appears and the peak vanishes.
