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.
Highlights
The astrophysical s-process is responsible for the production of about half of the abundance of the elements beyond iron in the Universe
Summary and outlook We have investigated the issue of the feasibility of the measurement of the important 13C(α, n)16O and 22Ne(α, n)25Mg reaction cross sections at energies in the region of the Gamow window in an underground lab
The neutron detector consists of an array of 3He tubes embedded in a PE neutron moderator which we believe is the best candidate for this type of measurement
