Recently the extremely neutron-rich systems 7H and 6H were studied in the direct 2H(8He,3He)7H [1,2] and 2H(8He,4He)6H [3] transfer reactions with a 26 AMeV secondary 8He beam produced at the fragment separator ACCULINNA-2 (FLNR, JINR)[4]. The missing mass spectra and center-ofmass angular distributions of 7,6H, as well as the momentum distributions of the 3H fragment in the 7,6H frames, were reconstructed. An experimental evidence is provided that two resonant states of 7H are located in its spectrum at 2.2(5) and 5.5(3) MeV relative to the 3H+4n decay threshold. Based on the energy and angular distributions, obtained for the studied 2H(8He,3He)7H reaction, the weakly populated 2.2 MeV peak is ascribed to the 7H ground state (g.s.). It is quite possible that the 5.5 MeV state is the 5/2+ member of the 7H excitation 5/2+–3/2+ doublet, built on the 2+ configuration of valence neutrons.
