Magnetic structure ofO17at high momentum

The elastic magnetic form factor of $^{17}\mathrm{O}$ has been measured for effective momentum transfers 2.47\ensuremath{\le}${\mathrm{q}}_{\mathrm{eff}}$\ensuremath{\le}3.65 ${\mathrm{fm}}^{\mathrm{\ensuremath{-}}1}$ by electron scattering. The form factor drops by almost three decades in this range. The data follow an extreme single-particle Woods-Saxon shell-model calculation. Many-body effects such as meson-exchange currents or core polarization do not seem to play a significant role in the q range of this experiment.
