利用夸克模型的重子-重子相互作用fss 2的能量无关形式，研究了中子-氘散射的低能破裂微分截面。这种相互作用几乎再现了中子入射能量En ≤ 65 MeV时由介子交换势预测的所有破裂微分截面。13 MeVnd散射的空间星星异常在我们的模型中也没有得到改善。在En = 22.7 − 65 MeV时对破裂微分截面的过高估计意味着，无论从实验上还是理论上，都有必要对各种破裂构型进行系统的研究。
The low-energy breakup differential cross sections of the neutron-deuteron (nd) scattering are studied employing the energy-independent version of the quark-model baryon-baryon interaction fss2. This interaction reproduces almost all the breakup differential cross sections predicted by the meson-exchange potentials for neutron incident energiesEn≤ 65 MeV. The space star anomaly of 13 MeVndscattering is not improved even in our model. Some overestimation of the breakup differential cross sections atEn= 22.7 − 65 MeV implies that systematic studies of various breakup configurations are necessary both experimentally and theoretically.
