With the results of the total photoabsorption
measurements realized by us in Frascati and Bonn, we could make the first
dispersion analysis in the nucleonics resonances region completely based
on experimental data. With this analysis we could get an accurate foward
Compton scattering amplitude in intermediate energies and the respective
foward Compton cross sections. Our calculations show an excellent agreement
with the experimental data where they are available. The differences between
the free and bound nucleon photo-interactions become more evident with
this analysis. |
