Accurate differential cross sections have been measured at specific beam energies and angles to be used in a method proposed previously for the simultaneous quantification of light elements (Z<11Z<11) present in evaporated liquid biological samples. Targets containing 1H, 7Li, 12C, 16O, 19F, 28Si and 197Au have been bombarded with 13 MeV 6Li3+ and 20 MeV 16O5+ beams. The 16O + 1H, 16O + 12C, 16O + 16O, 16O + 19F, 16O + 28Si and 16O + 197Au cross sections, shown to be consistent with the Rutherford formula predictions at 15° and 20°, have been used to determine cross sections for the 6Li + 1H, 6Li + 12C, 6Li + 16O, 6Li + 19F, 6Li + 28Si and 6Li + 197Au scatterings respectively at 17.5°, 24°, 25°, 26°, 28° and 30°. Although 6Li + 7Li cross sections have not been obtained from 16O + 7 Li cross sections, they have been determined from measured 6Li + 19F cross sections and, in addition, used to obtain 16O + 7Li cross sections at 15° and 20°. The reliability of the new cross sections determined in this investigation for the 6Li + 1H, 6Li + 7Li and 6Li + 19F scatterings is based on the Rutherford behavior of the measured 6Li + 197Au scattering data as expected and the consistency observed between the 6Li + 12C, 6Li + 16O and 6Li + 28Si cross sections obtained in this work and previously reported values. This research has important implications in applied physics.
