Single and multinucleon antiproton-$^{4}$He annihilation at rest

The p annihilation at rest in a NTP /sup 4/He-gas target has been studied by means of the Obelix spectrometer installed at the LEAR accelerator of CERN. Reactions with production of 2 pi /sup -/2 pi /sup +/, 2 pi /sup -/3 pi /sup +/, 2 pi /sup -/2 pi /sup +/p, 2 pi /sup -/ pi /sup +/2p, 2 pi /sup -/...

description The p annihilation at rest in a NTP /sup 4/He-gas target has been studied by means of the Obelix spectrometer installed at the LEAR accelerator of CERN. Reactions with production of 2 pi /sup -/2 pi /sup +/, 2 pi /sup -/3 pi /sup +/, 2 pi /sup -/2 pi /sup +/p, 2 pi /sup -/ pi /sup +/2p, 2 pi /sup -/3p (with p pi >80 MeV/c and p/sub 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 p/sup 4/He annihilations and branching ratios are evaluated for a number of reaction channels. (42 refs).
