%0 Journal Article %A Fraile Prieto, Luis Mario %T Measurement of very low (alpha,n) cross sections of astrophysical interest %D 2016 %@ 1742-6588 %U https://hdl.handle.net/20.500.14352/24368 %X The reactions C-13(alpha,n)O-16 and Ne-22(alpha,n)Mg-25 are the primary sources of neutrons for the astrophysical s-process. The feasibility of cross section measurements within the respective Gamow windows is discussed in quantitative terms for a 4 pi neutron counter, based on He-3 tubes and a neutron moderator, placed in an underground lab. %~
