Incoherent Neutral Pion Photoproduction onC12

Incoherent neutral pion photoproduction on 12C.

We present the first detailed measurement of incoherent photoproduction of neutral pions to a discrete state of a residual nucleus. The 12C(gamma,pi(0))(12)C*(4.4 MeV) reaction has been studied with the Glasgow photon tagger at MAMI employing a new technique which uses the large solid angle Crystal Ball detector both as a pi(0) spectrometer and to detect decay photons from the excited residual ...

Neutral Pion Photoproduction in a Regge Model

The reaction γp → πp is investigated in the energy range above the resonance region. The amplitudes include the leading Regge singularities in the cross-channel and correctly describe the differential cross section for beam energies above 4 GeV and for momentum transferred above −3 GeV. The energy dependence of the beam asymmetry and the reaction γn → πn seem is quantitative consistent with the...

Neutral-pion photoproduction on the deuteron.

Neutral kaon photoproduction on the deuteron has been investigated by including the final state effects and compared with the experimental data. Comparison shows that the models used in this calculation can reproduce the data in the Σ channel regions fairly well but still give over predictions in the Λ channel. It seems that the tensor target asymmetries are more suitable for studying the final...
