中文摘要：

在日本东京大学核研究中心的放射性离子束分离器上,利用逆运动学反应^1 H（^22 Ne,^22 Na）n产生了22 Na次级束。经分离器电磁系统的分离提纯后,获得了能量为（78.3±1.0）MeV的^22 Na次级束。实验靶站处次级束的强度达2.5×105 s^-1,其中22 Na的纯度好于90%。22 Na次级束已应用于与核天体物理Ne丰度异常问题相关的22 Na＋α共振散射实验研究。

英文摘要：

The 22Na secondary beam was produced via the ^1 H（^22Ne,^22Na）n reaction at the CNS Radioactive Ion Beam separator（CRIB）in University of Tokyo.After the separation and purification with the electric-magnetic system of the separator,a highquality ^22Na secondary beam was delivered with energy of（78.3±1.0）MeV,intensity of about 2.5×105 s^-1 and purity better than 90%.The 22Na secondary beam has been used for the study of the resonant scattering of 22 Na＋α,which is related to the neonextraordinary problem in nuclear astrophysics.
