~2H(~6He,~7Li)n反应角分布和~7Li的质子谱因子
Angular Distribution for ~2H(~6He,~7Li)n Reaction and Proton Spectroscopic Factor of ~7Li
【摘要】 在中国原子能科学研究院HI-13串列加速器次级束流线上,使用6He次级束首次测量了质心系能量为9.1 MeV的2H(6He,7Li)n反应角分布,并用扭曲波波恩近似(DWBA)进行理论分析,导出了7Li的质子谱因子为0.40±0.02。
【Abstract】 The angular distribution of the 2H(6He,7Li)nreaction was measured at Ecm=9.1 MeV for the first time using the secondary beam facility of HI-13 tandem accelerator.The experimental data were analyzed with distorted wave Born approximation(DWBA) calculation and the proton spectroscopic factor of 7Li was extracted to be 0.40±0.02.
