The unbound level structure of C has been studied using the 'OB(3He, t)' C reaction. Bombarding energy was 38.2 MeV and tritons were detected in an energy-loss spectrometer. In the seven spectra taken, at lab angl. es from 2, 5' to 30', the broad 6.60 MeV prominence was well fitted by a single Lorentzian-shaped peak, while the 5.28 MeV region was well fitted by two peaks. The excitation energies of these peaks were obtained using known levels in C, populated from the B impurity in the 8 target.NUCI EAR REACTIONS~oB(He, t); E=28.2 MeV; deduced level structure in broad peaks by fitting spectra; measured E", I' of levels found.In conjunction with a study of "Be via 9Be(d, P), '
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
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.
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.
