Properties of the 7He ground state studied by the 6He(d,p)7He reaction

The 7 He nucleus was studied using the 6 He[Formula: see text]He reaction in inverse kinematics at 29 [Formula: see text]MeV 6 He beam delivered by the ACCULINNA-2 fragment separator (FLNR, JINR). The registration of neutrons from [Formula: see text] decay made it possible to derive the 7 He ground state parameters, the decay energy of 0.38(2)[Formula: see text]MeV and width of 0.11(3)[Formula: see text]MeV.
