Abstract
The 2(1)(+) states of Sn-114,Sn-116 were excited in two consecutive experiments by means of Coulomb excitation in inverse kinematics on a Ni-58 target. A precise determination of the reduced transition probability B(E2; 0(g.s.)(+) -> 2(1)(+)) of Sn-114 relative to the well-known 2(1)(+) excitation strength in Sn-116 was achieved by comparing the relative projectile to target 2(1)(+) -> 0(g.s.)(+) decay intensities. The obtained B(E2 up arrow) value of 0.232(8)e(2)b(2) for Sn-114 confirms the tendency of large B(E2 up arrow) values for the light tin isotopes below the midshell Sn-116 that has been observed recently in various radioactive ion beam experiments. The result establishes most clearly the discrepancy between the current B(E2... (More)

The result establishes most clearly the discrepancy between the current B(E2 up arrow) value predictions from large-scale shell-model calculations and the experimental deviation, which commences already for the stable Sn-114 isotope.
