Coulomb excitation measurements of transition strengths in the

W ed escribe an experiment optimized to determine the transition probabilities for excitation of the first excited 2 + state in 132 Sn. The large excitation energy (4.04 MeV) and consequent small excitation cross-section, together with the modest beam intensity available makes this a challenging experiment. The preliminary result is B(E2; 0 + → 2 + ) = 0.11 ± 0.03e 2 b 2 . The high efficiency and generalized nature of the setup enabled us to also measure the first 2 + state in the two-neutron nucleus 134 Sn .W eh ave determined a value of B(E2; 0 + → 2 + ) = 0.029 ± 0.005e 2 b 2 which shows no sign of the asymmetry with respect to the
