Elastic and inelastic scattering of 'Li from "C have been measured at incident energies of 63 and 78.7 MeV. The experimental data were obtained over an angular range from 8„,=8' to 40'. Optical model parameters have been extracted by fitting the elastic scattering data, and deformation lengths have been obtained for the 'Li* (0.48 MeV) state and the "C~ (4.44 MeV) state. No single parameter set...
Local environments and lithium ion dynamics in the binary lithium silicide Li(12)Si(7), and the analogous germanium compound have been characterized by detailed (6)Li, (7)Li, and (29)Si variable temperature static and magic-angle spinning (MAS) NMR experiments. In the MAS-NMR spectra, individual lithium sites are generally well-resolved at temperatures below 200K, whereas at higher temperatures...
Comparison of the binding to DNA of 7-hydroxymethyl-12-methylbenza(a)anthracene and 7, 12-dimethylbenz(a)anthracene (DMBA) catalyzed by mouse embryo cells in culture or by rat liver microsomes indicates that the products formed are different for the two hydrocarbons. Thus, the hydroxy compound is not an intermediate in the binding of DMBA to DNA in these systems. Binding of the hydroxy compound...
