The work is dedicated to consequences of analyticity and unitarity of
the scattering amplitude. Using the
Gaussian quasipotential an equation for the scattering amplitude matrix is
obtained and formula is derived for the cross sections. The dependence of the
cross section and ratio of the real part of the amplitude in the forward
scattering to its imaginary part of on the momentum are discussed. The steep
Gaussian peak for cross section at small angles is followed by the exponential
(Orear) regime. Results from theoretical approach are compared with
experimental data.
