Electron and photon scattering (H05)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 514321794

In this project, a dedicated electron scattering program using the MAGIX spectrometers at MESA is planned to measure the proton form factors to unprecedented small momentum transfers, as well as a Compton scattering program at the Crystal Ball detector at MAMI, with the aim to improve on the extraction of the neutron polarizabilities by a factor of two. The latter quantities are at present a limiting uncertainty in the extraction of the nuclear charge radii from spectroscopy data on light muonic atoms.
