Measurement of the beam-helicity asymmetry in the p(e_pol,e'p)pi_0 reaction at the energy of the Delta(1232) resonance
P. Bartsch, D. Baumann, J. Bermuth +32
In a p(e_pol,e'p)pi_0 out-of-plane coincidence experiment at the 3-spectrometer setup of the Mainz Microtron MAMI, the beam-helicity asymmetry has been precisely measured around th…
Neutral pion threshold production at Q^2=0.05 GeV^2/c^2 and Chiral Perturbation Theory
Harald Merkel, Peter Bartsch, Dagmar Baumann +31
New data are presented on the p(e,e'p)π^0 reaction at threshold at a four-momentum transfer of Q^2=0.05 GeV^2/c^2. The data were taken with the three-spectrometer setup of the A1 C…
Precise Neutron Magnetic Form Factors
G. Kubon, H. Anklin, P. Bartsch +36
Precise data on the neutron magnetic form factor G_{mn} have been obtained with measurements of the ratio of cross sections of D(e,e'n) and D(e,e'p) up to momentum transfers of Q^2…
Self energies of the pion and the delta isobar from the ^3He(e,e'pi^+)^3H reaction
M. Kohl, M. Kuss, C. Rangacharyulu +7
In a kinematically complete experiment at the Mainz microtron MAMI, pion angular distributions of the He(e,e'H reaction have been measured in the excitation region of t…
