Abstract

Both nuclear reaction analysis and non-Rutherford elastic scattering have been widely used for analysis of light elements in solids; these two ion-beam methods complement more traditional analysis by Rutherford backscattering spectrometry. In this study, the reaction/scattering cross sections for 12C(p,p)12C, 12C(d,p)13C and 12C(α,α)12C at an angle of 150° are measured over relevant energy regions using thin films of carbon (5.8 μg/cm2) on silicate glass. The results are plotted and tabulated as a function of ion energy, with typical uncertainties of 4% for the cross section data. In addition, the angular distribution of the cross sections for the reaction 12C(d,p)13C at an ion energy of 0.94 MeV has also been determined from 100° to 170°. An example for the application of this reaction to SiC is given.
