20.500.12556/RUL-167871 Novel measurement of the neutron magnetic form factor from A = 3 mirror nuclei The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron’s electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties. We present results from a novel measurement of the neutron magnetic form factor using quasielastic scattering from the mirror nuclei $^3$H and $^3$He, where the nuclear effects are larger than for deuterium but expected to largely cancel in the cross-section ratios. We extracted values of the neutron magnetic form factor for low-to-modest momentum transfer, $0.6 < Q^2 < 2.9$ GeV$^2$, where existing measurements give inconsistent results. The precision and $Q^2$ range of these data allow for a better understanding of the current world’s data and suggest a path toward further improvement of our overall understanding of the neutron’s magnetic form factor. experimental nuclear physics eksperimentalna jedrska fizika true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-18 11:13:22 2025-03-18 11:13:23 2025-04-04 13:40:12 0000-00-00 00:00:00 2024 0 0 Str. 162501-1-162501-7 iss. 16 Vol. 132 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.1 0031-9007 10.1103/PhysRevLett.132.162501 229356035 PhysRevLett.132.162501.pdf PhysRevLett.132.162501.pdf 1 B1F75070C5E394BF0B3E47039F21E732 edf58821f146495077c09ab187d2b0342d3a0c53c3879375c2232206ace39b3d e2a7080d-03e2-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200754 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.132.162501 0 e840b7e8-03e2-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=200755 Fakulteta za matematiko in fiziko 0 0 0
