摘要：

Experimental search for 4H and 5H has been performed in the reactions 3H(t,p)5H, 2H(6He,3He)5H and 2H (t,p)4H. A resonance state situated at 1.8±0.1 MeV above the t+n+n decay threshold is obtained in the missing mass energy spectrum of the 5H nucleus. Also, there is an indication that another resonance located a t 2.7±0.1 MeV presents in this spectrum. Visible peak widths are governed mostly by the instrumental resolution, which came to about 0.4 MeV. We set an upper limit of 0.5 MeV on the true width of any of the two states. The resonance state of 4H with Eres=3.310.2 MeV and Γres,=4.1±0.3 MeV was obtained in the 2H(t,p)4H reaction.
