Abstract
The goal of the present project is to collect a reference set of measurements of electron and proton multiple elastic scattering with rigorous quantification of the statistical and systematic uncertainties. The electron and proton beams available at the Laboratório do Acelerador Linear (LAL) (energies continuously variable from 10 keV to 100 keV, and of 1.9 MeV and 5.0 MeV) and at the Lab…
