Excitation of the nuclear giant-dipole resonance by inelastic electron scattering

Abstract

The Goldhaber-Teller model of the giant dipole resonance of a nucleus has been cast in the language of the shell-collective model by using the generator coordinate method of Hill, Wheeler and Griffin. The wave function for the excited state found in this way has been used to evaluate explicitly the inelastic electron scattering form factor for excitation of the giant dipole resonance of the nucleus. The form factor found to be proportional to the elastic form factor multiplied by the momentum transfer. From an estimate of the bremsstrahlung background extracted from Fregeaus's data it is concluded that experimental investigation of the giant dipole resonance by electron scattering is feasible at optimum momentum transfer.
