Аннотация:small-angle neutron scattering data on aqueous solutions of wormlike micelles of an anionic surfactant of potassium oleate in the presence of low-molecular-weight KCl salt are studied for a wide range of surfactant concentrations. It is shown that, as the concentration of micelles in the network increases, the scattering intensity decreases because of the structure factor for small scattering vectors. The parameters of the local structure of micelles, which are independent of the surfactant concentration, are determined inthe range of average values of the scattering vectors. The values of the persistent length of wormlike micelles are obtained for a small concentration of potassium oleate. The correct persistent length of micelles is foundupon extrapolating
