首次用36.4MeV的二次6He束测量了2h （6He,7）键合反应的角分布。用实验数据的畸变波玻恩近似对计算的微分截面进行归一化，得到7li基态的质子光谱因子为0.42±0.06。讨论了通过精确地确定虚光势的体积积分，可以降低氘原子引起的单核子转移反应中提取光谱因子的不确定度。
The angular distribution of the2H (6He,7Linreaction was measured with a secondary6He beam of 36.4MeV for the first time. The proton spectroscopic factor of7Li ground state was extracted to be 0.42±0.06 by normalizing the calculational differential cross-sections with the distorted-wave Born approximation to the experimental data. It was discussed that the uncertainty of extracted spectroscopic factors from the one-nucleon transfer reactions induced by deuteron might be reduced by determining the volume integrals of imaginary optical potentials precisely.
