The Giant Dipole Resonance Effect in Coulomb Excitation of 10B

Abstract

Coulomb excitation of the O' 718 MeV, In = 1 +, first excited state of lOB has been studied using projectile excitation by 208Pb and observing the backward scattered particles. The results give a clear indication of the virtual excitation of the giant dipole resonance (GDR) as a second-order effect. The observed magnitude is consistent with the usual hydrodynamic model estimate and with a recent shell-model calculation.
