Abstract: The poorly known B(E2; 0<superscript>+</superscript> → 2<superscript>+</superscript>) values of <superscript>112</superscript>Sn and <superscript>114</superscript>Sn have been measured to high precision. Two Coulomb excitation experiments were performed to determine the reduced transition probabilities relative to <superscript>116</superscript>Sn in order to minimize the systematic errors. The obtained B(E2 ↑) values of 0:242(8) e²b² for <superscript>112</superscript>Sn and 0:232(8) e²b² for <superscript>114</superscript>Sn confirm the tendency of large B(E2 ↑) values for the lighter tin isotopes below the midshell <superscript>116</superscript>Sn that has been observed recently in various radioactive ion beam experiments.
