Abstract

High resolution electron scattering measurements on Pb208 have been performed at 90°and 160°, which allow the spatial reconstruction of transition charge densities and for the first time, transition current densities. The measurement covering the momentum transfer range of 0.5<q<2.6 fm-1 is supplemented by high momentum transfer data from Saclay, extending the data for some of the states up to a momentum transfer of 3.4 fm-1. We report on the first three J=5- states and the first J=7- state. Transition charge densities have been also extracted for the lowest J=2+, 4+, 6+, and 8+ states. The densities are compared to a number of theoretical calculations. Transverse electric currents are shown for the 5- states that indicate a quenching of the magnetization current similar to observations from other states but the absence of quenching in the convection current contribution. NUCLEAR REACTIONS Pb208(e,e) measured cross sections at 90°and 160°, 0.5q2.6 fm-1. Low lying J=2+, 4+, 6+, 8+, 5-, 7- states analyzed. Transition charge densities and current densities extracted in DWBA.
