A model for the form factors of the pion and of the transition ..gamma --> pi../sup 0/..omega.. is constructed on the basis of dispersion relations and the matrix N/D method. The unitarity condition is saturated by the ..pi pi.. and ..pi omega.. channels. The question is considered as to whether the rho'(1250) meson is required for agreement with the experimental data on the annihilation processes e/sup +/e/sup -/..--> pi../sup +/..pi../sup -/ and e/sup +/e/sup -/..--> pi../sup 0/..omega...
