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 coll ected 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. (C) 2000 Elsevier Science B.V. Al l rights reserved.
