Description

In this contribution, I present our latest developments in the study of neutron-rich nuclei. In particular, recent observations of a sharp low-energy structure in the four-neutron missing mass distribution [1] —following the fast removal of the $^4$He core from $^8$He nucleus—have sparked considerable interest. We have been able to explain this phenomenon as a consequence of neutron correlations arising from the emission of neutrons in a diffuse, weakly bound system.

Our earlier work relied on a simplified model of the neutron distribution within the $^8$He nucleus. In the present study, we aim to build on these foundations by developing a more realistic model of the $^8$He structure.

Additionally, we will discuss other neutron-rich systems, including neutron-rich hydrogen [3] and the $^{18-21}$B isotopes.
