Abstract

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.
