Section Data

We discuss novel dispersion relations in differential form, connecting real and imaginary parts of elastic scattering amplitudes and formally valid at any energy above the physical threshold. By means of fits to total cross section data from proton-proton and antiproton-proton scattering, we evaluate the corresponding ratio ρ between the real and imaginary parts of the forward amplitudes. We show that the results are exactly the same as those obtained through standard integral dispersion relations.

Wide Range

The scattering of free drift waves by drift vortices is investigated analytically in the Born and eikonal approximations. Scattering amplitudes and scattering cross-section are found for a wide range of parameters of the vortex and wave. It is shown that under certain conditions the wave–vortex interaction becomes very strong; that is, the scattering cross-section is much more than the vortex radius.
