Dipole polarizability is one of the fundamental properties of a nucleus, and can be studied in elastic scattering experiments performed at energies below the Coulomb barrier. For strongly bound nuclei the effect of dipole polarizabilty is usually negligible. However, for weakly bound nuclei, where the dipole strength extend to low excitation energies, it does play a major role.

This effect has already been examined in the scattering of the lightest weakly-bound stable nuclei, viz., d, 3He, and 7Li. At present work, we study the possibility to extract information on the coulomb dipole strenght for weakly bound unstable 6He nucleus, using the elastic scattering data obtained in low energy collisions with a 208Pb target. Three scattering energies have been used for this purpose. Continuum Discretized Coupled Channel (CDCC) calculations can reproduce the angular distribution of the data, and from this study we are able to gather information on the B(E1) distribution

This technique can be further extended for the weakly bound unstable nuclei close to the drip lines.
