Abstract

The p̄ annihilation at rest in a NTP ⁴He-gas target has been studied by means of the Obelix spectrometer installed at the LEAR accelerator of CERN. Reactions with production of 2π^-2π⁺, 2π^-3π⁺, 2π^-2π⁺p, 2π^-π⁺2p, 2π^-3p (with p_π > 80 MeV/c and p_p > 300 MeV/c) have been selected and single- and multinucleon annihilations identified. For the first time some known mesonic and baryonic resonances have been observed in p̄⁴ He annihilations and branching ratios are evaluated for a number of reaction channels.
