We present the first precision measurement of the spin-dependent asymmetry in the threshold region of 3He(e,e') at Q2 values of 0.1 and 0.2 (GeV/c)2. The agreement between the data and nonrelativistic Faddeev calculations which include both final-state interactions and meson-exchange current effects is very good at Q2 = 0.1 (GeV/c)2, while a small discrepancy at Q2 = 0.2 (GeV/c)2 is observed.
我们展示了在Q2值为0.1和0.2（GeV/c）2时，3He（e，e'）阈值区域中自旋相关不对称性的首次精确测量。在Q2 = 0.1（GeV/c）2时，数据与包括末态相互作用和介子交换电流效应的非相对论费德耶夫计算之间的一致性非常好，而在Q2 = 0.2（GeV/c）2时观察到了小的差异。
