| We investigated the low-lying spectroscopy of $^6$He via the 2-neutron transfer reaction induced by the $^8$He SPIRAL beam at 15.4 A.MeV on a proton-rich target. The light charged recoil particles produced by the direct reactions were measured using the MUST2 Si-strip telescope array. Two new resonances were observed above the known $2^+$ state in $^6$He, and the angular momentum transfer was deduced through the analysis of the angular distributions. Results are discussed in comparison with recent calculations of various nuclear structure theories which include the coupling to the continuum technique; some of them giving an understanding of the cluster correlations in the light weakly-bound nuclei. |
