质子滴线核⁸B的实验研究进展

摘要: 质子滴线核⁸B的最后一个质子的分离能只有0.137 5 MeV，被认为是最有可能具有质子晕结构的候选核之一，对其反应机制和奇特结构的研究吸引了人们的关注。针对⁸B的奇特结构和反应机制研究是一个非常有趣的课题，研究人员在包括反应截面、碎裂产物动量分布宽度、电四极矩、熔合截面及弹性散射等方面开展了大量的工作。但是⁸B的研究至今仍不够充分，需要从理论和实验上对其进行更深入的研究。

Abstract: The proton dripline nucleus ⁸B, with a proton separation energy of 0.137 5 MeV, is an archetypal proton halo candidate. The structure and mechanisms of reactions induced by this nucleus have received much attention from the experimental points of view. We review on the previous studies with measurements of reaction cross sections, longitudinal momentum distributions of fragments, electric quadruple moment, fusion cross sections, and elastic scattering angular distributions. More efforts, from both experimental and theoretical points of view, are needed to understand the nucleus ⁸B.
