DETERMINATION OF OXYGEN CONTENT IN HIGH Tc SUPERCONDUCTORS BY DEUTERON PARTICLE ACTIVATION ANALYSIS
利用氘粒子活化分析测定高温超导体中的氧含量

The experimental method for determining the oxygen content in high Tc superconduc tors is described in detail. This method is applied to determination of oxygen content in high Tc Y-Ba-Cu-O and Bi-Sr-Ca-Cu-O samples in which the stoichiometry is varied by reducing the copper and bismuth concentrations. The oxygen concentration is found to vary linearly with Cu (x= 0-0,2) and Bi (x= 0-0.4) deficiencies in YBa2Cu3(1-x)Oy and Bi2(1-x)Sr2CaCu2Oy respectively. X-ray powder diffraction measurements show that the compound of YBa2Cu3(1-x)Oy, is orthorhombic in the variation range of x=0-0.2
