Measurement of the analysing power and the differential cross section of the [formula omitted] charge-exchange reaction at LEAR

As part of a programme to study the spin structure of the pp→ nn channel, we have measured the analysing power A 0 n 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 t...

Description
Summary:As part of a programme to study the spin structure of the pp→ nn channel, we have measured the analysing power A 0 n 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.
