Abstract

The transfer reaction p\(8He, d\)7 He has been studied by correlational measurements, and an excited state of 7He was observed (E* = 2.9+/-0.3 MeV, γ = 2.2+/− 0.3 MeV)which decays mainly into 3n + 4He. Most likely, it has a structure with a neutron in an excited state coupled to the 6He core which itself is in the excited 2+ state.
