Precise determination of the proton magnetic radius from electron scattering data

Coulomb Corrections to Elastic Electron-Proton Scattering and the Proton Charge Radius

Recent values of the proton charge radius derived from the Lamb shift in electronic hydrogen tend to be larger than those from electron scattering. Therefore low-momentum-transfer scattering data from different groups and laboratories have been reanalyzed with Coulomb and recoil corrections included. This was done by calculating at each scattering angle and scattering energy the corresponding c...

The direct determination of the number-weighted mean radius and polydispersity from dynamic light scattering data

We compare results for the number-weighted mean radius and polydispersity obtained either by directly fitting number distributions to dynamic light scattering (DLS) data or by converting results obtained by fitting intensityweighted distributions. We find that results from fits using number distributions are angle independent. We find that converting intensity-weighted distributions is not alwa...

Direct determination of the number-weighted mean radius and polydispersity from dynamic light-scattering data.

We compare results for the number-weighted mean radius and polydispersity obtained either by directly fitting number distributions to dynamic light-scattering data or by converting results obtained by fitting intensity-weighted distributions. We find that results from fits using number distributions are angle independent and that converting intensity-weighted distributions is not always reliabl...

Form factor ratio from unpolarized elastic electron proton scattering

A reanalysis of unpolarized electron-proton elastic scattering data is done in terms of the electric to magnetic form factor squared ratio. This observable is in principle more robust against experimental correlations and global normalizations. The present analysis shows indeed that it is a useful quantity that contains reliable and coherent information. The comparison with the ratio extracted ...
