Direct reactions for nuclear astrophysics [PDF]

EPJ Web of Conferences, 2023
The neutron activation technique is a well established method to measure neutron capture cross sections relevant for the s-process. The 7Li(p,n) reaction at Ep = 1912 keV is often used as a neutron source since the energy distribution of the emitted ...
