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.
