Abstract

The Coulomb dissociation of 8B in the field of 208Pb was studied at around 50 MeV/u incident energy. The astrophysical S-factors for the 7Be(p,γ)8B reaction, a key of the solar neutrino production, were deduced. Possible mixture of the E2 components are expected to be small based on our measurement of angular distribution in a wide range. This supports our earlier analysis assuming pure E1 transitions.
