چکیده
Differential cross sections for elastic scattering of photons have been measured for 40Ca at energies of 58 and 74 MeV and for 16O and 4He at 61 MeV, in the angular range from 45◦ to 150◦. Evidence is obtained that there are no significant in-medium modifications of the electromagnetic polarizabilities except for those originating from meson exchange currents. PACS number: 25.20.Dc

Virtual Compton scattering off the nucleon has been studied in the one–loop approximation of the linear sigma model. The three generalized scalar polarizabilities of the nucleon have been calculated and compared with the existing theoretical predictions. In particular, we find that only two of the three scalar polarizabilities are independent observables.

The effective action for baryons in external electromagnetic fields is found on the basis of QCD string theory. The area law for large Wil-son loops is implied and we use the same string tension as for mesons to have a slope of baryon trajectories considing with the slope of me-son traectories. The asymmetric quark-diquark structure of nucleons is accepted and the approximation of straight-line...
