Projectile Polarization in the Coulomb Breakup of ${}^{6}{Li}$

The reaction

{}^{208}{Pb} ({}^{6}{Li}, α d)

{}^{208}{Pb}

was studied at

E_{{}^{6}{Li}} = 24 and 27

MeV by observing

d - α

coincidences for particles emitted into the same solid angle. At

E_{{}^{6}{Li}} = 24

MeV the reaction proceeds predominantly by a sequential process of Coulomb excitation of the 2.184-MeV,

J^{π} = 3^{+}

state, followed by breakup into

α

and

d

. When the strong dipole polarization of the

{}^{6}{Li}

projectile is taken into account, a

B (E 2; 1^{+} \to 3^{+}) = 24 e^{2}

{fm}^{4}

is found, in good agreement with a recent (

e, e^{'}

) experiment.
