The pd + npp charge exchange reaction has been studied at 1.15 GeV incident proton energy in a selected kinematical region. The distributions of two-proton invariant mass M,, , of angle of a single proton and the differential cross section da/dt of the (p, n) reaction are presented and compared with model predictions corrected for the acceptance of the experimental apparatus. We see no evidence of narrow (r < 30MeV/c2) peaks in the M,, interval 2.1-2.3 GeV/c'. The production of an intermediate A isobar in the primary (p, n) charge exchange and its subsequent absorption in a final state AN + pp process together with the background from quasi-free charge exchange scattering reasonably reproduces the general trends of the data.
