Coulomb Excitation of the 2·615 MeV (3?) and 4.086 MeV (2+) States of 208Pb

Abstract

Coulomb excitation studies of the 2�615 MeV (3-) and 4�086 MeV (2+) states of 208Pb have been carried out using 12C and 160 projectiles at various energies and scattering angles. Results for the 3- state are: B(E3;O+~3-) = O'611�O'012e2b 3 ; and the static quadrupole moment Q3 - = - O�34� O�15 e b, which is larger in magnitude than most theoretical calculations. Results for the 2+ state imply that Q2+ = -0�7�0�3 eb if a value for B(E2;0+~2+) determined from electron scattering work is assumed.
