论文摘要
背景：在连续的耦合通道法中，分解横截面（BUX）是作为多通道散射中不同通道的几个组件的混合而获得的。目的：我们的目标是提出一种将离散的BUX分解为每个通道组件的近似方法。该近似值称为“概率分离（P分隔）”。方法：举例来说，我们考虑$^{11} $是通过使用带有核心激发的三体模型（$^{10} \ Mathrm {Be}+n+n+\ \ \ \ Mathrm {t} $散射的，其中t是目标）。结构部分是由粒子旋转模型构造的，反应部分由扭曲的波出生近似（DWBA）描述。结果：通过与确切的计算进行比较，测试了P分隔的有效性。无论配置和/或$^{11} $ be的配置和/或共振位置如何，重现确切的BUX井。结论：此处提出的方法可以是将离散的BUX分解为四体或五体散射中的组件的替代方法，而严格的分解很难执行。
Background: In the continuum-discretized coupled-channel method, a breakup cross section (BUX) is obtained as an admixture of several components of different channels in multi-channel scattering. Purpose: Our goal is to propose an approximate way of decomposing the discretized BUX into components of each channel. This approximation is referred to as the "probability separation (P-separation)". Method: As an example, we consider $^{11}$Be scattering by using the three-body model with core excitation ($^{10}\mathrm{Be}+n+\mathrm{T}$, where T is a target). The structural part is constructed by the particle-rotor model and the reaction part is described by the distorted wave Born approximation (DWBA). Results: The validity of the P-separation is tested by comparing with the exact calculation. The approximate way reproduces the exact BUXs well regardless of the configurations and/or the resonance positions of $^{11}$Be. Conclusion: The method proposed here can be an alternative approach for decomposing discretized BUXs into components in four- or five-body scattering where the strict decomposition is hard to perform.
