Description
Light nuclei may exhibit clustering behavior, with nucleon correlations giving rise to distinct groupings of protons and neutrons typically forming α particles. In some instances, these clusters assemble into molecular-like structures, bounded by valence nucleons that are shared between the clusters analogously to electrons in an atomic covalent bond. Linear-chain configurations of α particles bonded by neutrons through π or σ bonds are theoretically predicted to exist.
In this contribution we report preliminary results concerning the study of the possible σ-bond linear chain configurations of $^{14}$C, studied through the reaction $^4$He($^{10}$Be,$^6$He) measured at LNS.
The excitation function is reconstructed by the analysis of the $^6$He energy spectra in the excitation energy range 19-26 MeV, where the sought structures are expected to exist.
