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 electron-helicity asymmetry in the quasi-elastic process
Tim Kolar, Sebouh J. Paul, Patrick Achenbach +43
We present measurements of the electron helicity asymmetry in quasi-elastic proton knockout from H and C nuclei by polarized electrons. This asymmetry depends on the f…
Operation and characterization of a windowless gas jet target in high-intensity electron beams
B. S. Schlimme, S. Aulenbacher, P. Brand +54
A cryogenic supersonic gas jet target was developed for the MAGIX experiment at the high-intensity electron accelerator MESA. It will be operated as an internal, windowless target…
Electron beam studies of light collection in a scintillating counter with embedded fibers
M. Lauß, P. Achenbach, S. Aulenbacher +28
The light collection of several fiber configurations embedded in a box-shaped plastic scintillating counter was studied by scanning with minimum ionizing electrons. The light was r…
