Angular distributions of the Coulomb dissociation of 8B in the field of 208Pb at Ein = 51.9 MeV/u were measured at 0° ≤ θ8 ≤ 10° and 0.5 ≤ Erel ≤ 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.
