Phys. Rev. 178, 2300–2301 (1969)High-Energy Limit for the Real Part of Forward Compton ScatteringReceived 7 October 1968; published in the issue dated February 1969 We investigate the contribution of a pole at α=0 to forward Compton scattering using finite-energy sum rules. We conclude that an experiment measuring the total photoabsorption cross section from ∼1 to 10-15 BeV with an accuracy of 5% will detect a contribution from such a pole whose magnitude is larger than 30% of the Thomson limit. © 1969 The American Physical Society URL:
