Abstract
Core-polarisation and meson-exchange current calculations have been
performed at 88Sr and 90Zr closed-shell cores to
determine the effective magnetic dipole operator for valence
orbitals. The values obtained show considerable core- and orbit-dependency.
The results are tested in shell-model calculations for magnetic
moments in N=50 and N=51 nuclides and the comparison with
experiment is satisfactory.
