The study of Coulomb excitation of 11Be to the first excited state in intermediate energy collisions with heavy targets is presented. The existing experimental data are reanalyzed by including the probability of projectile survival into the calculation of Coulomb excitation cross sections. The survival probabilities are calculated using a recently developed global optical model potential tailored in line with the double folding model. The extracted B(E1) values for the transition 1 / 2+→1 / 2- in 11Be are found to be slightly larger than those obtained so far using the b0 recipe in Coulomb excitation theory.
