¹³N 次级束的产生

摘要: 在北京串列加速器次级束流线上通过²H(¹²C,¹³N)n反应产生了可用于核天体物理研究的¹³N次级束。经磁刚度选择以及速度选择，准直后的次级束纯度达91%，能量为(70.2±0.7) MeV，强度约为10 s^-1•pnA^－1，可用来进行逆几何转移反应的实验测量。

Abstract: A ¹³N secondary beam to be used in the study of nuclear astrophysics was produced by the ²H(¹²C,¹³N)n reaction using the secondary beam line of the HI-13 tandem accelerator at Beijing. The energy of the ¹³N secondary beam is （70.2±0.7） MeV, with a purity of 91 % and the intensity of about 10 s^－1•pnA^-1 after collimation. The beam can be used for the study of transfer reaction in inverse kinematics.
