论文摘要
我们使用双重折叠方法来确定$^{10} $ be-nucleus碰撞的光电位，以计算真实部分和kramers-kronig分散关系，以得出虚构部分。作为显微镜输入，我们在近代到领先的顺序上使用手性有效场理论核子核子相互作用，结合了最新的核这个密度。有了这些电势，我们计算出外来核10的弹性散射横截面是各种目标，并将它们与实验进行比较。没有任何拟合参数，我们可以与数据达成良好的一致性。对于在光目标上发生冲突，我们观察到与短距离物理学相关的明显不确定性，而对于不确定性的重度目标仍然很小。
We present a determination of optical potentials for $^{10}$Be-nucleus collisions using the double-folding method to compute the real part and Kramers-Kronig dispersion relations to derive the imaginary part. As microscopic inputs we use chiral effective field theory nucleon-nucleon interactions at next-to-next-to-leading order combined with state-of-the-art nucleonic densities. With these potentials, we compute elastic scattering cross sections for the exotic nucleus 10 Be off various targets, and compare them to experiment. Without any fitting parameter, we obtain good agreement with data. For collisions on light targets, we observe significant uncertainty related to the short-range physics, whereas for heavy targets that uncertainty remains small.
