论文摘要
我们使用Halo有效场理论和动力学近似值扩展了先前对11BE的分裂计算，以包括有效的10BE-N-TARGET力。该力的构建是为了说明10BE的虚拟激发到其低洼的2+激发态。在12C目标上分解的情况下，这改善了中子能和角光谱的描述，尤其是在11BE 5/2+状态附近。通过微调三体力的范围参数，还可以获得3/2+ 11BE状态区域中数据的合理描述。这种对三体力范围的敏感性是由控制三体力引起的11BE S-d-d态转变的重叠积分的结构产生的。
We extend our previous calculation of the breakup of 11Be using Halo Effective Field Theory and the Dynamical Eikonal Approximation to include an effective 10Be-n-target force. The force is constructed to account for the virtual excitation of 10Be to its low-lying 2+ excited state. In the case of breakup on a 12C target this improves the description of the neutron-energy and angular spectra, especially in the vicinity of the 11Be 5/2+ state. By fine-tuning the range parameters of the three-body force, a reasonable description of data in the region of the 3/2+ 11Be state can also be obtained. This sensitivity to the three-body force's range results from the structure of the overlap integral that governs the 11Be s-to-d-state transitions induced by the three-body force.
