Abstract

The total photoabsorption cross sections for ¹H, ²H, and ³He have been measured for incident photon energies ranging from 200 to 800 MeV. The ³He data are the first for this nucleus. By using the large acceptance detector DAPHNE in conjunction with the tagged photon beam facility of the MAMI accelerator in Mainz, cross sections of high precision have been obtained. The results show clearly the changes in the nucleon resonances in going from ¹H to ³He. In particular, for the D₁₃ region the behavior for ³He is intermediate between that for ¹H, ²H, and heavier nuclei. This will provide a strong constraint to the theories that are presently being developed with a view to explaining the apparent "damping" of higher resonances in heavy nuclei.
