The aim of this research is to determine the reaction cross-section for one of the most important fusion reactions in the sun that is directly connected to the solar neutrino problem: 3He(4He,γ)7Be. For this, we use the Accelerator Mass Spectrometry (AMS) technique at the Koffle accelerator of the Weizmann Institute. As a first step, we have tested our set-up by measuring the number of atoms of 7Be obtained from 7Li(p,n)7Be reaction. The sensitivity proved to be better than 10-14, allowing us to proceed towards an independent measurement with a different approach of this astrophysical important cross section. PACS: 26.65.+t, 29-27.-a, 07.75.+h.
