✦ Synopsis

The meson (K and ~') exchange currents for the hypernuclear magnetic moments are calculated using the effective Lagrangian method. The seagull diagram, the mesonic diagram and the ~excitation diagram are considered. The A-N exchange magnetic moments for 5aHe and A=6 hypernuclei are calculated employing the harmonic oscillator shell model. It is found that the two-body correction is about -9% of the single particle value for 5aHe. The ~-exchange current, induced only in the ~)-excitation diagram, is found to give dominant contribution for the isovector magnetic moments of hypemuclei with A = 6. (~) 1997 Elsevier Science B.V.
