摘要
在北京串列加速器次级束流线上通过2 H(7Li,8Li) 1H逆运动学反应产生了用于核天体物理研究的8Li次级束。准直后的次级束纯度达到 80 %以上 ,对于 44MeV的7Li强度约为 3 0s- 1·pnA- 1,可以用来进行逆几何转移反应的实验测量。
The 8Li secondary beam to be used in the study of nuclear astrophysics is produced by the 2H( 7Li, 8Li) 1H reaction in inverse kinematics using the secondary beam line of the HI 13 tandem accelerator at China Institute of Atomic Energy. The purity of the collimated 8Li beam is better than 80%, the intensity is about 30 s -1 ·pnA -1 for 44 MeV 7Li beam. The beam can be used for the study of transfer reactions in inverse kinematics.
