| Title | Quantum Monte Carlo calculations of electromagnetic moments and transitions in $\bm{A\leq9}$ nuclei including meson-exchange currents derived from chiral effective field theory | ||||
| Abstract | Quantum Monte Carlo calculations of electromagnetic moments and transitions are reported for $A\leq9$ nuclei. The realistic Argonne $v_{18}$ two-nucleon and Illinois-7 three-nucleon potentials are used to generate the nuclear wave functions. Contributions of two-body meson-exchange current (MEC) operators are included for magnetic moments and $M1$ transitions. The MEC operators have been derived in both a standard nuclear physics approach and a chiral effective field theory formulation with pions and nucleons including up to one-loop corrections. The two-body MEC contributions provide significant corrections and lead to very good agreement with experiment. Their effect is particularly pronounced in the $A=9$, $T=3/2$ systems, in which they provide up to $\sim 20\%$ ($\sim 40 \%$) of the total predicted value for the $^9$Li ($^9$C) magnetic moment. | ||||
