Measurements of the γ* p --> Δ(1232) reaction at low Q2
N. Sparveris, S. Stave, P. Achenbach +29
We report new p measurements in the resonance at the low momentum transfer region utilizing the magnetic spectrometers of the A1 Collabor…
Consistent threshold pi0 electro-production at Q^2=0.05, 0.10, and 0.15 GeV^2/c^2
H. Merkel, P. Achenbach, C. Ayerbe Gayoso +22
New, accurate data are presented on the near threshold p(e,e'p)pi^0 reaction in the range of four-momentum transfers between Q^2=0.05 and 0.15GeV^2/c^2. The data were taken with th…
Virtual Compton Scattering measurements in the transition
N. F. Sparveris, P. Achenbach, C. Ayerbe Gayoso +30
We report on new H measurements in the resonance at (GeV/c) carried out simultaneously with H. It is the lowest for w…
Separated cross sections in π^0 electroproduction at threshold at Q^2 = 0.05 GeV^2/c^2
M. Weis, P. Bartsch, D. Baumann +26
The differential cross sections σ_0=σ_T+εσ_L, σ_{LT}, and σ_{TT} of π^0 electroproduction from the proton were measured from threshold up to an additional center of mass energy of…
Beam-helicity asymmetry in photon and pion electroproduction in the Delta(1232) resonance region at Q^2= 0.35 (GeV/c)^2
A1 Collaboration, I. K. Bensafa, P. Achenbach +40
The beam-helicity asymmetry has been measured simultaneously for the reactions (e p \to e p γ) and (e p \to e p π^0) in the resonance region at 0.35 (GeV/c). T…
Determination of quadrupole strengths in the gamma*p-->Delta(1232) transition at Q2= 0.20 (GeV/c)2
N. F. Sparveris, P. Achenbach, C. Ayerbe Gayoso +29
We report new precise p measurements at the peak of the resonance at $Q^2=\unit[0.20](GeV/c)^2$ performed at the Mainz Microtron (MAMI). The…
