A Coupled-Channels Study of ${}^{11}Be$ Coulomb Excitation

Abstract

We study the effects of channel coupling in the excitation of ${}^{11}Be$ 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 $\halfm$ state in ${}^{11}Be$ projectiles. We show that the experimental results cannot be explained, unless very unusual parameters are used.
