在E（in）= 51.9 MeV/u的Pb-208场中的B-8的库仑解离的角分布在0度小于或等于θ（8）小于或等于10度和0.5小于或等于E（rel）小于或等于2.25 MeV时测量。使用量子力学方法分析数据，其中包括E1，E2和l = 2的核振幅。虽然系统的影响可能很大，提取的E2分量似乎比迄今为止报道的任何理论预测都要小得多。
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.
