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。
At the radioactive ion beam splitter at the Nuclear Research Center at the University of Tokyo, Japan, 22 Na secondary beams were generated using the inverse kinematic reaction 1 H (22 Ne, 22 Na) n. After separation and purification of the separator electromagnetic system, a 22 Na secondary beam with an energy of (78.3 ± 1.0) MeV was obtained. The intensity of the secondary beam at the target site reached 2.5 × 105 s-1, of which the purity of 22 Na was better than 90%. 22 Na secondary beams have been used in 22 Na + α resonance scattering studies related to the Abnormity of nuclear astrophysics.
