AB The cosmological 7Li problem arises from the signi cant discrepancy of about afactor 3 between the predicted primordial 7Li abundance and the observed one. The mainprocess for the production of 7Li during Big-Bang nucleosynthesis is the decay of 7Be. Manykey nuclear reactions involved in the production and destruction of 7Be were investigated inattempt to explain the 7Li de cit but none of them led to successful conclusions. However,some authors suggested recently the possibility that the destruction of 7Be by 3He and 4He mayreconcile the predictions and observations if missing resonant states in the compound nuclei 10Cand 11C exist. Hence, a search of these missing resonant states in 10C and 11C was investigatedat the Orsay Tandem-Alto facility through 10B(3He,t)10C and 11B(3He,t)11C charge-exchangereactions respectively. After a short overview of the cosmological 7Li problem from a nuclearphysics point of view, a description of the Orsay experiment will be given as well as the obtainedresults and their impact on the 7Li problem.
