(e,en) Coincidence Studies of the Giant Multipole Resonances ofPb208

Abstract
The isoscalar monopole and quadrupole giant multipole resonances of Pb208 have been studied in the excitation region of 9 to 16 MeV by coincident electron scattering. Concentrations of strength have been found at 10.4 and 14.2 MeV, in reasonable agreement with the predictions of mean-field theory. The measurements reported are the first nuclear-structure investigation carried out by use of the (e,en) reaction.
