[3][4][5][6][7] given for the existence of low-lying 0 + states in deformed actinide nuclei that did not have the properties of a β-vibration or of a pairing vibration.Evidence that the [505]11/2 − oblate orbital is associated with reduced pairing was first presented by J.D. Garrett et al. [8,9]. But a direct test of the underlying microscopic structure of |0 + 2 is required if we are to be completely confident in our interpretation of these states. a e-mail: jfss@tlabs.ac.za In many cases the single-particle orbitals dominating the configuration of a nuclear state can be ascertained from its population in direct reactions. However the |0 + 2 levels in N = 90 nuclei are very weakly populated in
1. The isolation of aspalathin, the principal phenolic constituent in the leaves of Aspalathus linearis, is described and its properties are discussed. 2. The compound has been identified as 3'-C-beta-d-glucopyranosyl-2',3,4,4',6'-pentahydroxydihydrochalcone by the preparation and analysis of various derivatives, by photochemical oxidation to 2,3-dihydroiso-orientin and by nuclear-magnetic-resonance studies.
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.
