Peripheral pn production and decay angular distributions in the reaction pi /sup -/p to (pn)p at 12 GeV/c incident momentum

The reaction pi /sup -/p to (pn)p/sub s/, where p/sub s/ is a slow proton, was measured at 12 GeV/c incident momentum with the CERN-OMEGA spectrometer. Both antiproton and proton were identified uniquely by electronics information. 1844 events with four-momentum transfer squared in the range 0.13<...

description The reaction pi /sup -/p to (pn)p/sub s/, where p/sub s/ is a slow proton, was measured at 12 GeV/c incident momentum with the CERN-OMEGA spectrometer. Both antiproton and proton were identified uniquely by electronics information. 1844 events with four-momentum transfer squared in the range 0.13<or= mod t mod <or=0.33 GeV/sup 2/ and with invariant masses M(pn) up to 2.5 GeV were obtained. The corresponding cross section in this t range is determined to be sigma =4+or-0.4 mu b. Extrapolating the differential cross section over the whole t range assuming d sigma /dt approximately exp(5.3 t) a cross section of sigma =9.3+or-2.0 mu b is estimated. Comparison is made with data on pi /sup -/p to (pp)n/sub s/ (where n/sub s/ is a slow neutron) in the same t range. (12 refs).
