A coupled-channels study of 11Be Coulomb excitation

We study the effects of channel coupling in the excitation of 11Be projectiles incident on heavy targets. The contribution to the excitation from the Coulomb and the nuclear fields in peripheral collisions are considered. Our results are compared with recent data on the excitation of the 12− state in 11Be projectiles. We show that the experimental results cannot be explained, unless very unusual parameters are used.
