The reduced transition probability B(E2; 0) to the first excited 2 state of the neutron-rich nucleus Te, with two protons and two neutrons outside the doubly magic Sn core, was measured via Coulomb excitation at relativistic energies at the RIKEN Radioactive Isotope Beam Factory. In the experiment, Te isotopes impinged on a 950 mg/cm Au target. The measured B(E2) value, 0.191(26) eb, is in good agreement with the result of a recent experiment employing low-energy Coulomb excitation. Because of the high statistics gathered in this work the error of the deduced B(E2) value is dominated by the systematic uncertainties involved in the analysis of Coulomb excitation experiments at beam energies around 150 MeV/u. These uncertainties were assessed for the first time and will be of use for future experiments at RIBF.
