Abstract

Highly excited states of 6He are sought in the reactions involved in the absorption of stopped pions by 10,11B nuclei. Several levels in 6He are observed for the first time. A state with E x ≈ 9.3(2) MeV and Γ ≈ 1.0(4) MeV is seen to form in two reactions: 10B(π, pt)X and 11B(π, dt)X. Two states are seen to form in the 10B(π, pt)X reaction channel at energies above the threshold of 6He decay into two tritons (E x ≥ 12.3 MeV): one state with E x = 22(1) MeV, Γ = 2.7(1.4) MeV and the other with E x = 27.0(8) MeV, Γ = 2.5(1.1) MeV.
