Abstract

We present Quantum Monte Carlo calculations of magnetic form factors in A=610A=6-10 nuclei, based on Norfolk two- and three-nucleon interactions, and associated one- and two-body electromagnetic currents. Agreement with the available experimental data for 6^6Li, 7^7Li, 9^9Be and 10^{10}B up to values of momentum transfer q3q\sim 3 fm1^{-1} is achieved when two-nucleon currents are accounted for. We present a set of predictions for the magnetic form factors of 7^7Be, 8^8Li, 9^9Li, and 9^9C. In these systems, two-body currents account for 4060%\sim40-60\% of the total magnetic strength. Measurements in any of these radioactive systems would provide valuable insights on the nuclear magnetic structure emerging from the underlying many-nucleon dynamics. A particularly interesting case is that of 7^7Be, as it would enable investigations of the magnetic structure of mirror nuclei.
