Methodology for Accurate Oxygen Distribution Analysis and Its Application to YBa2Cu3Ox Thin Films Using 16O(α, α)16O 3.045 MeV Resonance Reaction

Abstract
The enhancement factor of oxygen of 16O(α, α)16O resonance for a Rutherford backscattering cross section has been investigated using SiO2 films of various thicknesses. A new procedure to accurately extract the resonant oxygen height from a raw spectrum has been proposed. With this procedure, the dependence between the film thicknesses and resonant signals has been investigated, and was found to agree well with a computer simulation within experimental error. Using the enhancement factor, the depth dependence of oxygen concentration in the YBa2Cu3O x /MgO systems has been estimated accurately. Estimations of the accuracy of elastic backscattering analysis are also given.
