摘要：

Two consecutive Coulomb excitation experiments were performed to excite the 2(1)(+) states of Sn-112,Sn-116 using a Ni-58 beam. For Sn-112 a B(E2 up arrow) value of 0.242(8) e(2) b(2) has been determined relative to the known value of Sn-116. The present value is more precise than previous measurements and shows a clear discrepancy from the expected parabolic dependence between the doubly magic nuclei Sn-100 and Sn-132. It implies that the reduced transition probabilities are not symmetric with respect to the midshell mass A = 116.
