Ion beam analysis of oxygen distribution in superconducting YBa2Cu3Ox
Abstract
It has been shown that by combining the elastic scattering of protons and Rutherford scattering of α particles, the total composition and oxygen distribution of superconducting YBa2Cu3Ox films and bulk samples can be analyzed. The non-Rutherford scattering due to the 16O(p,p0)16O reaction enhances at the bombarding energy of 2.3 MeV the elastic scattering cross section by a factor of 5 over the cross section of the Rutherford scattering and makes it possible to determine the oxygen distribution in the matrix of heavy elements Y, Ba, and Cu.
