Photoproduction of π0-Mesons from the Nucleon and Deuteron
The photoproduction of π0-mesons from the nucleon and deuteron has been studied for incidents of photon energies up to 1.5 GeV. By using the MAID-2007 model for the process on the nucleon, we predict results for the unpolarized and helicity-dependent total cross sections of the semi-exclusive reacti...
