Measurement of the Ge() cross section up to 300~keV at the CERN n_TOF facility

A. Gawlik, C. Lederer-Woods, the n_TOF collaboration

Neutron capture data on intermediate mass nuclei are of key importance to nucleosynthesis in the weak component of the slow neutron capture processes, which occurs in massive stars…

A direct measurement of the 17O(a,g)21Ne reaction in inverse kinematics and its impact on heavy element production

M. P. Taggart, C. Akers, A. M. Laird +33

During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. A…
