Determination of the forward Compton scattering amplitudes for C and Pb

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

The forward Compton scattering amplitudes for carbon and lead have been calculated from total photoabsorption cross-section data by using dispersion relations. The results show a large difference between the scattering amplitudes for nuclei and the free nucleon, above the Δ region. Difference between carbon and lead is also evident. The forward Compton scattering cross-sections have been calculated and compared with the available data. The Weise sum rule is discussed together with the predictions of a recent theoretical model.
