The level structure of 87y has been studied using in-beam v-ray spectroscopic methods. Many previously unknown states have been observed. Members of the rc(gg/2)v(g9/2) -2 multiplet are identified. The results are discussed in terms of the weak-coupling model.
Reaction and total cross sections for ϩ and Ϫ on targets of 2 H, 6 Li, C, Al, Si, S, and Ca have been measured for beam energies from 42 to 65 MeV. The cross sections are proportional to the target mass at 50 MeV, consistent with transparency to these projectiles. The cross sections are compared to theoretical calculations.PACS number͑s͒: 25.80.Ls TR ϭ R ϩ EL ϩ C ϩ NCI , ͑3͒
scite is a Brooklyn-based startup 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 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.
