Abstract
A new measurement of the differential cross section and of the analysi ng power A(0n) of the charge-exchange reaction ($) over bar pp --> ($) over bar nn at 875 MeV/c is presented. The A(0n) data cover the entir e angular range and constitute a considerable improvement over previou sly published data, both in the forward and in the backward hemisphere . The cross-section data cover only the backward region, but are uniqu e at this energy. A careful study of the long-term drifts of the appar atus has allowed to fully exploit the good statistics of the data.
