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.

Its important to notice that the observed peak is consistent with the reported in Ref.\ \cite{Duer:2022} and previous Ref.\ \cite{Kisamori:2016} results.
Its important evidence for the tetraneutron resonance at low energies above the 4n decay threshold obtained at forward angles in the reaction of alpha core knockout from the $^8$He beam.
\section{Conclusion} \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.
