[sup 8]B 的库仑离解截面——[sup 208]Pb([sup 8]B,[sup 7]Be [ital p])[sup 208]Pb 反应——使用 46.5 MeV/核子能量的 [sup 8]B 放射性束测量，以及 [sup 7]Be([ital p]) 的截面。 p],γ)[sup 8]B 在低能量下发生捕获反应； [ital E][亚厘米]=0.6[减]1.7 MeV。提取的天体物理 [ital S][sub 17] 因子与 Vaughn [ital et] [ital al] 测量的值一致。和 Filippone [ital et] [ital al]。这一结果鼓励进一步的实验研究扩展到较低的相对能量，以重新确定与 [sup 8]B 太阳中微子通量相关的 [ital S][sub 17] 值。
The cross section for Coulomb dissociation of [sup 8]B---the [sup 208]Pb([sup 8]B,[sup 7]Be [ital p])[sup 208]Pb reaction---was measured using a [sup 8]B radioactive beam of 46.5 MeV/nucleon energy, and the cross section for the [sup 7]Be([ital p],[gamma])[sup 8]B capture reaction was deduced at low energies; [ital E][sub c.m.]=0.6[minus]1.7 MeV. The extracted astrophysical [ital S][sub 17] factors were found to be consistent with the values measured by Vaughn [ital et] [ital al]. and Filippone [ital et] [ital al]. This result encourages further experimental studies extended to lower relative energies for a new determination of the [ital S][sub 17] value relevant to the [sup 8]B solar neutrino flux.
