Lifetimes for the lowest three transitions in the nucleus ' Xe have been measured using the recoil distance technique. Our data indicate that the lifetime for the 2, + -+0, + transition is more than a factor of 2 lower than the previously adopted value and is in agreement with more recent measurements performed on this nucleus.
High-spin states in the odd-A 113 Sn nucleus have been investigated with the 100 Mo( 18 O, 5n) reaction at 94 MeV using the Chalk River 8 array. Three decoupled (⌬Iϭ2) rotational bands extending to spins I in the range (63/2-69/2)ប have been identified and connected to known low-lying states. Experimental observations for the most extended band have been interpreted as evidence for smooth band termination. Theoretical calculations performed within a configuration-dependent shell-correction approach suggest that all three bands are built upon deformed two-particle-two-hole proton excitations across the Zϭ50 shell gap.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
