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.

Static Quadrupole

The reorientation effect in Coulomb excitation has been used to measure the static quadrupole moment Q2+ and B(E2;0+->2+) for the 1�779 MeV first excited state of 28Si. The results obtained are Q2+ = +15�5�3�4 efm2 and B(E2;0+->2+) = 326�20 e2fm4 ? The value obtained for Q2+ confirms the results of other recent determinations using the reorientation effect, and the B(E2; 0+ -> 2 +) value is in excellent agreement with the mean value deduced from previous lifetime determinations. Shell model and Hartree-Fock calculations of Q2+ both give a good account of the experimental result.

Static Quadrupole

The reorientation effect in Coulomb excitation has been used to measure the static quadrupole moment of the first 2+ level of 56Fe. Using beams of 4He and 16O on thin highly enriched targets and observing the spectrum of scattered particles in semiconductor detectors, we have obtained directly the ratios of inelastic to elastic cross sections. The measurements give[Formula: see text]The ambiguity arises from uncertainty in the relative signs of interfering matrix elements.For the case of He scattering, DWBA calculations were carried out to check the energy region where nuclear interaction begins to appear.
