Antiproton-neon annihilation at 57 MeV/c

The pNe annihilation cross section is measured for the first time in the momentum interval (53/63) MeV/c. About 9000 pictures collected by the Streamer Chamber Collaboration (PS179) at LEAR-CERN have been scanned. Four events are found, corresponding to sigma /sub ann /=2210+or-1105 mb. The result i...

Sumario:The pNe annihilation cross section is measured for the first time in the momentum interval (53/63) MeV/c. About 9000 pictures collected by the Streamer Chamber Collaboration (PS179) at LEAR-CERN have been scanned. Four events are found, corresponding to sigma /sub ann /=2210+or-1105 mb. The result is compared to the set of measurements presently available in the region of low p momentum. (18 refs).
