Resumo

As part of a programme to study the spin structure of the pp→nn channel, we have measured the analysing power A0n and the differential cross section at an incident antiproton beam momentum of 704 MeV/c. The analysing power exhibits a remarkable angular dependence, which is poorly reproduced by the existing potential models.
