Evidence for shape coexistence in ${}^{120}$Sn from the first $0_3^{+}$ lifetime measurement

F. Wu, C. Andreoiu, V. Karayonchev +14

The lifetime of the $0_3^{+}$ state in ${}^{120}$Sn was measured for the first time applying the fast-timing technique following thermal neutron capture. The mean lifetime of $τ= 50(7…
