Non-forward radiative corrections to electron-carbon scattering
M. Mihovilovič, A. B. Weber, P. Achenbach +37
Radiative corrections to elastic scattering represent an important part of the interpretation of electron-induced nuclear reactions at small energy transfers, where they make for a…
Measurement of the α-particle monopole transition form factor challenges theory: a low-energy puzzle for nuclear forces?
S. Kegel, P. Achenbach, S. Bacca +30
We perform a systematic study of the -particle excitation from its ground state to the resonance. The so-called monopole transition form factor is investigated v…
Measurements of the induced polarization in the quasi-elastic process in non-coplanar kinematics
Sebouh J. Paul, Tim Kolar, Tilen Brecelj +44
We report measurements of the induced polarization of protons knocked out from H and C via the reaction. We have studied the dependence of $\v…
Measurement of the Generalized Polarizabilities of the Proton at Intermediate
H. Fonvieille, J. Beričič, L. Correa +35
Background: Generalized polarizabilities (GPs) are important observables to describe the nucleon structure, and measurements of these observables are still scarce. Purpose: This pa…
New Insight in the -Dependence of Proton Generalized Polarizabilities
J. Beričič, L. Correa, M. Benali +35
Virtual Compton scattering on the proton has been investigated at three yet unexplored values of the four-momentum transfer : 0.10, 0.20 and 0.45 GeV, at the Mainz Microtr…

The Mu3e experiment is searching for the charged lepton flavour violating decay , aiming for an ultimate sensitivity of one in decays. In an…
Quasi-elastic polarization-transfer measurements on the deuteron in anti-parallel kinematics
Sebouh J. Paul, David Izraeli, Tilen Brecelj +41
We present measurements of the polarization-transfer components in the H reaction, covering a previously unexplored kinematic region with large positive (ant…
The influence of Fermi motion on the comparison of the polarization transfer to a proton in elastic and quasi-elastic scattering
S. Paul, T. Brecelj, H. Arenhövel +35
A comparison between polarization-transfer to a bound proton in quasi-free kinematics by the A knockout reaction and that in elastic scattering off a free proto…
