 Obviously, this spectrum shape can not be described just as a contribution of the 4-body phase space volume, see the orange dotted curve in Fig.\ \ref{fig:mm_4n} (b), indicating the presence of some resonance states of 4n lying at 3-4\,MeV above the 4n decay threshold.

 \section{Conclusion}
 
+The $^2$H($^8$He,$^6$Li)4n reaction was studied at forward angles.
+The observed peak at 3-4 MeV above the 4n threshold is in agreement with Ref.\ \cite{Duer:2022,Kisamori:2016}.
+The obtained results are pushing the investigation of the neutron clusters.
+The configuration of the detector setup specifically for such reaction and improved neutron detection efficiency is demanded in the future experiments.
+The latter will not also increase statistics but also will allow to study neutron cluster decays in full kinematics reconstructed by the invariant mass methods.
