| Abstract: | We show that there is a reduction of the magnetic transition strength at high momentum transfer due to core polarization. This accounts substantially for the observed reduction of 50% of the Jπ=12? and 14? transitions in 208Pb. The core polarization does not affect the shape of the high J form factors in the vicinity of their main peaks. However, a significant q-dependent effect is predicted for the ground state M1 moment of 207Pb. |
