E1 strength in Pb-208 within the shell model

The dipole response of the doubly-magic 208Pb was studied in a photon-scattering experiment at the electron linear accelerator ELBE with bremsstrahlung produced at a kinetic electron energy of 14.0 MeV. The present (gamma,gamma') data combined with (gamma,n) data from literature are compared with results of calculations using a quasiparticle random-phase approximation and with results of shell-model calculations. It turns out that the shell model describes the experimental low-lying E1 strength as well as the giant dipole resonance well by applying a small spreading width only.
