| Summary: | Green's function Monte Carlo calculations of magnetic moments and $M1$ transitions including two-body meson-exchange current (MEC) contributions are reported for $A\leq7$ nuclei. The realistic Argonne $v_$ two-nucleon and Illinois-2 three-nucleon potentials are used to generate the nuclear wave functions. The two-body meson-exchange operators are constructed to satisfy the continuity equation with the Argonne $v_$ potential. The MEC contributions increase the $A$=3,7 isovector magnetic moments by 16\% and the $A$=6,7 transition rates by 17--34\%, bringing them into very good agreement with the experimental data. |
