The (p)overbarNe annihilation cross section is measured for the first time in the momentum interval (53 divided by 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(anm) = 2210 +/- 1105 mb. The result is compared to the set of measurements presently available in the region of low (p)overbar momentum.

Abstract
The (p)overbarNe annihilation cross section is measured for the first time in the momentum interval (53 divided by 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(anm) = 2210 +/- 1105 mb. The result is compared to the set of measurements presently available in the region of low (p)overbar momentum.
