Title: Quantum Monte Carlo calculations of magnetic moments and M1 transitions in A {le} 7 nuclei including meson-exchange currents.

Abstract

Green's function Monte Carlo calculations of magnetic moments and M1 transitions including two-body meson-exchange current (MEC) contributions are reported for A 7 nuclei. The realistic Argonne v{sub 18} 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{sub 18} potential. The MEC contributions increase the A = 3,7 isovector magnetic moments by 16% and the A = 6,7 M1 transition rates by 17-34%, bringing them into very good agreement with the experimental data.
