在这篇文章中，我们将描述中子和质子从9C和7Be中的去除，这是两个特别有趣的核进入核合成pp链[1，2]。在过去的二十年里，中子和质子去除反应已经被用来探测奇异核的单粒子结构。核的平行动量分布可以给出核子初态的角动量和自旋信息，而总的去除截面对初态波函数的渐近部分和反应机制敏感。由于敲除反应是一个外围反应，可以从中提取单粒子波函数的渐近归一化常数（ANC），因此它被用作间接方法来获得8B（p，γ）9C或7Be（p，γ）8B等反应的速率。核子移除最近被HiRA合作应用于剩余的“核心”超出滴线的情况，例如8C和6Be，未被一个或多个质子束缚，并且...
In this contribution, we will describe neutron and proton removal from 9C and 7Be which are two particularly interesting nuclei entering the nucleo-synthesis pp-chain [1, 2]. Neutron and proton removal reactions have been used in the past twenty years to probe the single-particle structure of exotic nuclei. The core parallel-momentum distribution can give information on the angular momentum and spin of the nucleon initial state while the total removal cross section is sensitive to the asymptotic part of the initial wave function and also to the reaction mechanism. Because knockout is a peripheral reaction from which the Asymptotic Normalization Constant (ANC) of the single-particle wave function can be extracted, it has been used as an indirect method to obtain the rate of reactions like 8B(p,γ)9C or 7Be(p,γ)8B. Nucleon removal has recently been applied by the HiRA collaboration [3] to situations in which the remaining “core” is beyond the drip line, such as 8C and 6Be, unbound by one or more protons, and...
