Description

In this contribution, I present a recent theoretical study of the magnetic structure of light nuclei; namely, I will discuss the calculation of magnetic moments and form factors in $6\le A\le 10$ systems using the Norfolk model-- a chiral effective field theory based nuclear interaction-- and its consistent electromagnetic current operators. To study these observables, I employ quantum Monte Carlo techniques to stochastically solve the many-nucleon Schr\"{o}dinger Equation. Using the Norfolk model, it is possible to understand in detail the role of many-nucleon currents and correlations in describing low-energy magnetic moment data. The discussion of magnetic form factors will cover how these same two-body currents impact predictions of elastic electron scattering, as well as the role of different multipolarities in describing experimental data. Finally, I will show results for predicted magnetic form factors in light radioisotopes and will discuss the interpretation of an interesting effect predicted for pairs of mirror nuclei.
