Enhanced $0_{g.s.}^+ \to 2_1^+$ E2 Transition Strength in $^{112,114}$Sn

The poorly known B(E2; 0(+) -> 2(+)) values of (112)Sn and (114)Sn have been measured to high precision. Two Coulomb excitation experiments were performed to determine the reduced transition probabilities relative to (116)Sn in order to minimize the systematic errors. The obtained B(E2 up arrow)...

Sumario:The poorly known B(E2; 0(+) -> 2(+)) values of (112)Sn and (114)Sn have been measured to high precision. Two Coulomb excitation experiments were performed to determine the reduced transition probabilities relative to (116)Sn in order to minimize the systematic errors. The obtained B(E2 up arrow) values of 0.242(8) e(2)b(2) for (112)Sn and 0.232(8) e(2)b(2) for (114)Sn confirm the tendency of large B(E2 up arrow) values for the lighter tin isotopes below the midshell (116)Sn that has been observed recently in various radioactive ion beam experiments.
