Abstract
Measurements of relative differential cross sections have been obtained for elastic scattering of He3 nuclei from Pb208 at energies well below the Coulomb barrier. The measurements show deviations from Rutherford scattering, which are attributed to electric polarization of the He3 nuclei in the Coulomb field of Pb208. The deduced value of the electric polarizability for He3 is α=0.250±0.040 fm3. This result is significantly larger than expected from measurements of cross sections for He3 photodisintegration.Keywords
