Abstrakt: A resonance state situated at 1.8±0.1 and, most likely, another state positioned at 2.7±0.1 MeV above the t+n+n decay threshold were observed in the missing mass energy spectrum of the 5H nucleus produced in the reaction 3H(t,p)5H. The peak located close to $$E_{^5 H} = 1.8$$ MeV also was seen in the 5H spectrum obtained from the energy distributions of 3H nuclei emitted in the reaction 2H(6He,5H)3He. The width (Γobs ≤ 0.5 MeV) obtained for the two 5H resonance states is surprisingly small. A state of 4H with E res = 3.3 MeV and γ2 = 2.3 MeV was obtained in the reaction 2H(t,p)4H from the proton spectrum. [ABSTRACT FROM AUTHOR]
