Vv. Shklyar et al., BREMSSTRAHLUNG IN INTERMEDIATE-ENERGY NUCLEON REACTIONS WITHIN AN EFFECTIVE ONE-BOSON EXCHANGE MODEL, Nuclear physics. A, 628(2), 1998, pp. 255-274
Within a covariant effective one-boson exchange model for the T matrix
of NN interactions we present detailed calculations of bremsstrahlung
cross sections for proton-proton and proton-neutron reactions at beam
energies in the 1 GeV region. Besides pure bremsstrahlung processes w
e consider photons from Delta decays and contributions from the eta --
> gamma gamma process, At beam energies above 700 MeV the Delta decay
channel dominates the spectra at large photon energies, where the inte
rference between non-resonance processes and the Delta decay channel b
ecomes also important, Low energy photons stem from pure bremsstrahlun
g processes, The available experimental data at 730 MeV beam energy is
well described, We extrapolate the model down to 280 MeV, where more
detailed experimental data exist, and find agreement with angular dist
ributions. (C) 1998 Elsevier Science B.V.
