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…
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…
Measurement of the recoil polarization in the p (\vec e, e' \vec p) pi^0 reaction at the Δ(1232) resonance
Th. Pospischil, P. Bartsch, D. Baumann +39
The recoil proton polarization has been measured in the p (\vec e,e'\vec p) pi^0 reaction in parallel kinematics around W = 1232 MeV, Q^2 = 0.121 (GeV/c)^2 and epsilon = 0.718 usin…
The focal plane proton-polarimeter for the 3-spectrometer setup at MAMI
T. Pospischil, P. Bartsch, D. Baumann +46
For experiments of the type A(\vec e,e'\vec p) the 3-spectrometer setup of the A1 collaboration at MAMI has been supplemented by a focal plane proton-polarimeter. To this end, a ca…
