摘要:

在CERN的n_TOF空间中子源上完成第二条中子束线和相关实验区(EAR2)之后,计划并执行了几项实验。EAR2中可用的高瞬时中子通量允许研究与出口通道中的带电粒子的中子指示反应,即使采用由少量短寿命放射性同位素制成的靶。在成功测量了7 Be(n,α)α截面之后,我们又对7 Be(n,p)7 Li反应进行了研究,以提供与大爆炸核合成(BBN)相关的截面数据,试图解决宇宙学锂丰度问题。本文介绍了在这样的测量和表征的实验装置。

英文摘要:

Following the completion of the second neutron beam line and the related experimental area (EAR2) at the n_TOF spallation neutron source at CERN, several experiments were planned and performed. The high instantaneous neutron flux available in EAR2 allows to investigate neutron indiced reactions with charged particles in the exit channel even employing targets made out of small amounts of short-lived radioactive isotopes. After the successful measurement of the 7Be(n,α)α cross section, the 7Be(n,p)7Li reaction was studied in order to provide still missing cross section data of relevance for Big Bang Nucleosynthesis (BBN), in an attempt to find a solution to the cosmological Lithium abundance problem. This paper describes the experimental setup employed in such a measurement and its characterization.
