本文研究了在卡塔尼亚南国家实验室的SMP 13串列加速器上利用现有束流传输线在飞行中产生次级~ 8Li放射性束流的问题。该方法包括在动量过滤的开关磁铁的8Li离子发射回的质量中心的2 H(7 Li,p)8Li反应,然后由飞行时间标记的偏转离子。详细介绍了与星系核合成有关的8Li(4 He,n)11B反应的实验过程和初步结果。
The in flight production of a secondary8Li radioactive beam using the existing beam transport lines at the SMP13 Tandem accelerator of the Laboratori Nazionali del Sud in Catania is studied. The method consists in the momentum filtering by a switching magnet of the8Li ions emitted backward in the centre of mass of the2H(7Li,p)8Li reaction, followed by a time-of-flight tagging of the deflected ions. Details of the experimental procedures and preliminary results of the8Li(4He,n)11B reaction study relevant for pregalactic nucleosynthesis are presented and discussed.
