Description
Two consecutive Coulomb excitation experiments were performed to excite the 21+ states of 112,116Sn using a 58Ni beam. For 112Sn a B(E2↑) value of 0.242(8) e2 b2 has been determined relative to the known value of 116Sn. The present value is more precise than previous measurements and shows a clear discrepancy from the expected parabolic dependence between the doubly magic nuclei 100Sn and 132Sn. It implies that the reduced transition probabilities are not symmetric with respect to the midshell mass A=116.
