Production of the 1S0 diproton in the pp->pp pi0 reaction at 0.8 GeV
Production of the 1S0 diproton in the pp->pp pi0 reaction at 0.8 GeV
The pp -> pp pi(0) differential cross section has been measured with the ANKE spectrometer at COSY-Julich for pion cms angles between 0 degrees and 15.4 degrees at a proton beam energy of 0.8 GeV. The selection of diproton pairs with an excitation energy E-pp < 3 MeV ensures that the final pp...

The pp -> pp pi(0) differential cross section has been measured with the ANKE spectrometer at COSY-Julich for pion cms angles between 0 degrees and 15.4 degrees at a proton beam energy of 0.8 GeV. The selection of diproton pairs with an excitation energy E-pp < 3 MeV ensures that the final pp system is dominantly in the spin-singlet S-1(0) state. The kinematics are therefore very similar to those of pp -> d pi(+) but with different spin and isospin transitions. The cross sections are over two orders of magnitude smaller than those of pp -> d pi(+) and show a forward dip that is even stronger than that seen at lower energies. The results should provide a crucial extra test of pion production models in nucleon-nucleon collisions. (c) 2006 Elsevier B.V. All rights reserved. |
