Structure of light atomic nuclei is a object of renewed interest - part of it stems from the recent advent of ab initio calculations, but part is also due to the exotic configurations found at high excitation energies and/or in neutron-rich nuclei. Halo states, nuclear molecules and other exotic clustering are just some of the examples of such unusual quantum structures found and studied in the recent decades.
The clustering in general is known to occur at energies around the particle (cluster) decay thresholds, which are usually well above the neutron decay thresholds. At these energies the experimental data on neutron decay widths is far from complete, and these are essential for systematic understanding of the mentioned phenomena.
We propose therefore to measure the neutron induced sequential particle decay on number of light nuclei (9Be, 12C, 16O, ...), up to very high excitation energies. Since the neutron beam is not monoenergetic, we propose to detect all the particles coming from the reaction, and by doing that, reconstruct the incoming energy of neutrons. The measurement could be performed with a rather small and portable detector set-up, so that it can be placed at the position where flux of neutrons is optimal for the DAQ we have. The results would complement our measurements performed elsewhere with charged particle beams.
