We have studied the properties of the unbound isotope of helium 7He, using the 2H(8Li,3He)7He reaction. When combined with prior measurements of the 2H(6He,p)7He reaction the data present a consistent picture for the low‐lying excited states of 7He, specifically the negative parity sequence 3/2 (ground state) 1/2 (first‐excited) and 5/2 (second‐excited). The shapes but not the absolute magnitudes of the angular distributions are reproduced by ab‐initio theory coupled with a DWBA reaction framework.
