“…For example, the (α, n) reactions on short-lived nuclides that synthesize heavy elements in the weak r-process are now being measured using a variety of complementary techniques such as the MUSIC detector at Argonne National Laboratory and NSCL [189], along with the HABANERO neutron counter and SECAR recoil separator at NSCL [188]. Similarly, (p, n) reactions are being measured at energies of interest for νp-process nucleosynthesis using the SECAR recoil separator with neutron coincidences [261].…”

Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements. This white paper summarizes progress and status of the field, the new open questions that have emerged, and the tremendous scientific opportunities that have opened up with major advances in capabilities across an ever growing number of disciplines and subfields that need to be integrated. We take a holistic view of the field discussing the unique challenges and opportunities in nuclear astrophysics in regards to science, diversity, education, and the interdisciplinarity and breadth of the field. Clearly nuclear astrophysics is a dynamic field with a bright future that is entering a new era of discovery opportunities.

“…Research efforts for the development of a suitable technique to study and experimentally constrain the (n,p) and (p,n) reaction rates of short-lived nuclei [5] are ongoing at FRIB (Facility for Rare Isotope Beams). The measurement of the 58 Fe(p,n) 58 Co reaction in inverse kinematics at SECAR (SEparator for CApture Reactions) described in this work is the most recent experimental effort towards this direction.…”

The formation of nuclei in slightly proton-rich regions of the neutrino-driven wind of core-collapse supernovae could be attributed to the neutrino-p process (νp-process). As it proceeds via a sequence of (p,γ) and (n,p) reactions, it may produce elements in the range of Ni and Sn, considering adequate conditions. Recent studies identify a number of decisive (n,p) reactions that control the efficiency of the νp-process. The study of one such (n,p) reaction via the measurement of the reverse (p,n) in inverse kinematics was performed with SECAR at NSCL/FRIB. Proton-induced reaction measurements, especially at the mass region of interest, are notably difficult since the recoils have nearly identical masses as the unreacted projectiles. Such measurements are feasible with the adequate separation level achieved with SECAR, and the in-coincidence neutron detection. Adjustments of the SECAR system for the first (p,n) reaction measurement included the development of new ion beam optics, and the installation of the neutron detection system. The aforementioned developments along with a discussion on the preliminary results of the p(58Fe,n)58Co reaction measurement are presented.
