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.
