Nuclear reactions induced by neutrons play a key role in several astrophysical scenario like primordial nucleosynthesis, s and r process and so on. From an experimental point of view, their reaction cross sections and reaction rates at astrophysically relevant temperatures are usually a hard task to be measured directly. Nevertheless big efforts in the last decades have led to a better...
Lithium is the heaviest element produced during Big Bang nucleosynthesis. The amount produced can be predicted through the cosmic microwave background and measured through old metal-poor stars. Li has two stable isotopes, with Li-7 being more abundant than Li-6. In particular, the detection of Li-6 in old metal-poor halo stars contradicts the Big Bang nucleosynthesis prediction by 5 orders of...
