Abstract: Two particles coincidences of identified ¹⁵C and unidentified particle from ⁹Be + ¹³C collisions are analyzed as three particles exit channel ⁹Be(¹³C, ¹⁵Cα)³He and ⁹Be(¹³C, ¹⁵Cτ)⁴He. In spectrum of α-τ relative energy ⁷Be well-known states with E_x(⁷Be) = 4.7, 6.73 and 9.2 МeV are identified and other at E_x(⁷Be) ∼11.6, 13, (14.1), 15.7 and 18 MeV are also possible. Situation that states of ⁷Be with E_x(⁷Be) = 7.21 and ∼ 10 МеV are not observed in those reactions are explained by their not α-τ cluster structure.
