Radiative pi0 photoproduction on protons in the Delta+(1232) region
S. Schumann, B. Boillat, E. J. Downie +56
The reaction gamma p -> p pi0 gamma' has been measured with the Crystal Ball / TAPS detectors using the energy-tagged photon beam at the electron accelerator facility MAMI-B. Energ…
Incoherent pion photoproduction on C
C. M. Tarbert, D. P. Watts, P. Aguar +57
We present the first detailed measurement of incoherent photoproduction of neutral pions to a discrete state of a residual nucleus. The CC r…
Determination of the η mass with the Crystal Ball at MAMI-B
A. Nikolaev, P. Aguar-Bartolomé, J. Ahrens +59
A new precise determination of the η meson mass is presented. It is based on a measurement of the threshold for the γp -> pη reaction using the tagger focal-plane microscope det…
Neutron skin of Pb from Coherent Pion Photoproduction
C. M. Tarbert, D. P. Watts, D. I. Glazier +57
Information on the size and shape of the neutron skin on Pb has been extracted from coherent pion photoproduction cross sections measured using the Crystal Ball together wi…
Beam-Helicity Asymmetries in Double Pion Photoproduction off the Proton
D. Krambrich, F. Zehr, A. Fix +58
Beam-helicity asymmetries have been measured at the MAMI accelerator in Mainz in the three isospin channels , and $\vecγp\to Ï^{+…
Study of and photoproduction at MAMI
V. L. Kashevarov, P. Ott, S. Prakhov +87
The reactions and have been measured from their thresholds up to the center-of-mass energy GeV with the tagged-photon facilities at the Mainz Mi…
