Neutron-induced reactions play a fundamental role in astrophysics, in particular for the understanding of the origin of the heavy elements in the Universe, which is one of the main open questions in science and a fascinating topic of research.
Thus far, most of the existing neutron-capture cross section measurements have been made on stable isotopes, with only a handful of experiments available on radioactive samples in the relevant energy range for astrophysics (1 keV to 100 keV). However, there is an increasing need for neutron-capture data on radioactive species. This is especially true for the understanding of explosive nucleosynthesis environments, such as the rapid-neutron capture (r-) process in neutron-star mergers, and also for relatively new nucleosynthesis processes, such as the intermediate (i-) process of nucleosynthesis and the recently proposed n-process operating in core-collapse supernovae explosions.
With the advent of new facilities and very large neutron fluxes, measurements on radioactive nuclei become increasingly accessible, albeit requiring a significant effort in the development and customization of dedicated instrumentation. In this presentation I will summarize some recent ideas and innovative measuring techniques that could be exploited at the future DONES facility, thereby maximizing the scientific impact of the installation and enabling the opportunity to perform forefront nuclear-physics research, without compromising the primary aim of the installation.
