Abstracts
It is shown that in relativistic theory the partial wave amplitudes f_l analytical functions of the angular momentum l. The asymptotic behavior of the scattering amplitude as a function of the transferred momentum is determined by the nearest singularities of f_l. An expression for the scattering amplitude at arbitrary transferred momenta is obtained in terms of f_l and satisfies the Mandelstam equation which relates the spectral function and the absorption terms. The behavior of the scattering amplitude at high energies is discussed.
