Measurement of electric polarizabilities of light nucleus (nucleons)

The measurement of the electromagnetic polarizabilities have been given extensive attention, which is also a fresh field of the experimental nuclear physics. Now we will use the method - the light nucleus scattered by the heavy nucleus at energies below the Coulomb barrier to precisely and systematically measure the polarizabilities of the light nucleus. We hope we can solve the inconsistency among the results of the 3 He polarizabilities and extract the 4 He polarizabilities by our experiment. It is useful to mention that our experiment now is a supplement to the future experiment on SLEGS.
