论文摘要
对于单中性光环核,用于中间能量的弹性散射和分裂的横截面具有相似的角度依赖性。反应激发和分解反应模型优雅地解释了这一功能。这也导致了可观察到的新反应的想法,可以研究松散结合的核系统的结构:比率。可观察到的可观察到的是不同反应通道的角度分布的比率,即。弹性散射和分解,这取消了对反应机制的大部分依赖性;特别是,它对模拟弹丸靶向相互作用的光电位的选择不敏感。这种新的可观察到对弹丸的结构非常敏感。在本文中,我们回顾了比率方法及其扩展到低光束能量和质子 - 哈洛核。
For one-neutron halo nuclei, the cross section for elastic scattering and breakup at intermediate energy exhibit similar angular dependences. The Recoil Excitation and Breakup (REB) model of reactions elegantly explains this feature. It also leads to the idea of a new reaction observable to study the structure of loosely-bound nuclear systems: the Ratio. This observable consists of the ratio of angular distributions for different reaction channels, viz. elastic scattering and breakup, which cancels most of the dependence on the reaction mechanism; in particular it is insensitive to the choice of optical potentials that simulate the projectile-target interaction. This new observable is very sensitive to the structure of the projectile. In this article, we review the Ratio Method and its extension to low beam energies and proton-halo nuclei.
