Abstract: A new method is proposed to search for highly excited states of light nuclei. Quite narrow resonance states of ⁶He are found in the system of two tritons at E _x1 = 15.8 ± 0.6 MeV with Γ₁ = 1.1 ± 0.6 MeV and at E _x2 = 20.9 ± 0.3 MeV with Γ₂ = 3.2 ± 1.5 MeV. In addition, an indication of the existence of a state at E _x3 = 31.1 ± 1.0 MeV with Γ₃ = 6.9 ± 2.3 MeV is obtained.
