Approach: Theoretical


Weakly bound and unbound three-body nuclei are studied by using the pseudostate method within the hyperspherical formalism. After introducing the theoretical framework, the method is applied first to the $\boldsymbol{^9}$Be nucleus, showing a good agreement with the available data for its low-lying dipole response. Then, recent results on the structure and decay of the two-neutron emitters $\boldsymbol{^{26}}$O and $\boldsymbol{^{16}}$Be are presented. In particular, the role of the $\boldsymbol{n}$-$\boldsymbol{n}$ correlation in shaping their properties is discussed.

The paper is nicely written in a pretty clean and didactic way. It is easy to follow, and when needed, the proper references are cited.

The content is scientifically relevant and sound, investigating a hot topic in nuclear few-body physics, such as the structure and properties of light nuclei in the vicinity of the driplines.

I consider the paper can be published in its present form.
