The corresponding measurement is considered to be carried out at the future MESA facility in Mainz with beam=155MeV. We find that a combination of a 0.3% precise measurement of the parity-violating asymmetry at forward angles with a 10% measurement at backward angles will allow to determine the weak charge and the weak radius of 12C with 0.4% and 0.5% precision, respectively. These values could be improved to 0.3% and 0.2% for a 3% backward measurement. This experimental program will have impact on precision low-energy tests in the electroweak sector and nuclear structure.6 p.application/pdfeng(c) American Physical Society, 2020Radi (Os)Estructura nuclearFísica nuclearRadius (Anatomy)Nuclear structureNuclear physicsinfo:eu-repo/semantics/article7452352024-11-04info:eu-repo/semantics/openAccess
