Abstract

With the R³B-LAND setup at GSI we have measured exclusive relative-energy spectra of the Coulomb dissociation of ¹⁸C at a projectile energy around 425A MeV on a lead target, which are needed to determine the radiative neutron-capture cross sections of ¹⁷C into the ground state of ¹⁸C. Those data have been used to constrain theoretical calculations for transitions populating excited states in ¹⁸C. This allowed to derive the astrophysical cross section σ^∗_nγ accounting for the thermal population of ¹⁷C target states in astrophysical scenarios. The experimentally verified capture rate is significantly lower than those of previously obtained Hauser-Feshbach estimations at temperatures T₉ ≤ 1 GK. Network simulations with updated neutron-capture rates and hydrodynamics according to the neutrino-driven wind model as well as the neutron-star merger scenario reveal no pronounced influence of neutron capture of ¹⁷C on the production of second- and third-peak elements in contrast to earlier sensitivity studies.
