摘要:

我们报道了利用氘核的准弹性电蜕变测量中子电荷形状因子的新方法。在850兆电子伏的能量的纵向极化的电子从同位素纯,高度极化的氘气目标散射。散射电子和符合中子由Bates大型接受光谱仪环形(BLAST)探测器测量。在四个动量转移$Q^{2}=0.14$,0.20,0.29和0.42(GeV/c)$^{2}$下,从束靶矢量不对称性$A_{ed}^{V}$中提取中子形状因子比$G^{n}_{E}/G^{n}_{M}$。

英文摘要:

We report new measurements of the neutron charge form factor at low momentum transfer using quasielastic electrodisintegration of the deuteron. Longitudinally polarized electrons at an energy of 850 MeV were scattered from an isotopically pure, highly polarized deuterium gas target. The scattered electrons and coincident neutrons were measured by the Bates Large Acceptance Spectrometer Toroid (BLAST) detector. The neutron form factor ratio $G^{n}_{E}/G^{n}_{M}$ was extracted from the beam-target vector asymmetry $A_{ed}^{V}$ at four-momentum transfers $Q^{2}=0.14$, 0.20, 0.29 and 0.42 (GeV/c)$^{2}$.
