Abstract

The reactions 13C(α, n)16O and 22Ne(α, n)25Mg 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 4π neutron counter, based on 3He tubes and a neutron moderator, placed in an underground lab.
