Giant magnetic dipole states in /sup 208/Pb observed in the /sup 207/Pb + n reaction

High-resolution neutron transmission and elastic-scattering measurements on /sup 207/Pb have revealed a concentration of p-wave strength in /sup 208/Pb which is mainly accounted for by J/sup ..pi../ = 1/sup +/ resonances. The sum of the ground-state radiative widths for these resonances is ..sigma..GAMMA/sub ..gamma..//sub 0/ = 7.2 eV which agrees well with a one-particle--one-hole theoretical prediction which locates a fragment of the giant M1 resonance at 7.50 MeV with GAMMA/sub ..gamma..//sub 0/ = 9.3 eV.
