摘要：

Angular distributions of the Coulomb dissociation of B-8 in the field of Pb-208 at E(in) = 51.9 MeV/u were measured at 0 degrees less than or equal to theta(8) less than or equal to 10 degrees and 0.5 less than or equal to E(rel) less than or equal to 2.25 MeV. The data were analyzed using a quantum mechanical method where E1, E2 and l = 2 nuclear amplitudes are included. Although systematic effects could be large, the extracted E2 components appear to be considerably smaller than any theoretical predictions reported so far.
