Description

At the end of its life, a massive star can collapse into a proto-neutron star leading to a supernovae explosion. The neutrino flux released during the collapse and the explosion is so significant that the probability of a neutrino interacting with a nucleus can actually influence the nucleosynthesis, the so-called ν-process. The ν-process is believed to explain the origins of light element, especially the one of $^{11}B$, which is not fully understood. It has been proposed as a candidate for its production in core collapse supernovae. Neutrino triggered reaction lead to the production of (^11)B via the reaction $^7Li(α,γ)^{11}B$. The cross section of $^7Li(α,γ)^{11}B$ is then critical to estimate the contribution of the ν-process to $^{11}B$ abundance, constraining at the same time the ν-process. This reaction was recently studied at Notre Dame in the range of energy relevant to the ν-process and the result of this experiment will be presented.
