Charge-exchange anti-pp→anti-nn differential cross-sections between 546 and 1287 MeV/c

The differential cross section of the charge-exchange reaction p → n has been measured at the CERN Low Energy Antiproton Ring (LEAR) at seven momenta in the range 546-1287 MeV/c. A pentanol polarized target has been used and the neutron and the antineutron have been detected in coincidence. The data cover most of the angular range
