摘要
Precise measurements of the differential cross section and the beam polarization asymmetry E have been obtained by the GRAAL collaboration for the (gamma) over right arrow + p --> n + p and the (gamma) over right arrow + p --> pi(0) + p reactions, at incoming photon energies up to 1.48 GeV. Preliminary data are presented and compared with different theoretical calculations. First measurements of the E observable are also available for the (gamma) over right arrow + p --> K(+)Lambda reaction channel.
