Abstract
There is a well-known forward peak in the np forward charge-exchange cross section, for momentum transfers |t|≲mπ2. We have performed an experiment to look for analogous behavior in the reaction p̅p→n̅n. The data cover the kinematical region 0≤|t|≤1.5mπ2 at an incident antiproton momentum of 1.80 GeV/c. A forward peak is observed, which is estimated (from results of other experiments) to be considerably smaller than that for np charge exchange. This result can be understood in terms of interference between one-pion exchange and exchange of a particle with even G parity.
