Description

The 7He nucleus was studied using the 6He(d, p)7He reaction in inverse kinematics at 29A·MeV 6He beam delivered by the ACCULINNA-2 fragment separator (FLNR, JINR). The registration of neutrons from 7He → n +6 He decay made it possible to derive the 7He ground state parameters, the decay energy of 0.38(2) MeV and width of 0.11(3) MeV. The forward-backward asymmetry in the neutron emission from unbound states of 7He has been found. That implies the presence of a positive parity wave in the 7He spectrum.
