The B(E1) strength of ¹¹Be extracted from the Coulomb excitation measurements

We have extracted the B(E1) strength for the transition 1/2(+) -> 1/2(-) occurring in Be-11 from the recent Coulomb excitation measurements using the nonrelativistic and intermediate-energy Coulomb-excitation (IECE) theory and have found that the results of IECE theory are in good agreement with the adopted value of B(E1). When the survival probability of the projectile is taken into account the agreement between the calculated and the adopted value of B(E1) strength improves further. We have also studied the effect of diffuseness parameter of survival probability on the B(E1) strength.
