✦ Synopsis

The effective atomic numbers and electron densities of YBa 2 Cu 3 O 7Àd superconductor at 59.5, 65.2, 77.1, 94.6, 122 and 136 keV were calculated by using the measured mass attenuation coefficients. Measurements were made by performing transmission experiments in a well-collimated narrow beam geometry set-up by employing Si(Li) detector with a resolution of 0.16 keV at 5.9 keV. These values are found to be in good agreement with theoretical values calculated based on XCOM data. The observed crystal structure of YBa 2 Cu 3 O 7Àd superconductor is close to the theoretical structure. Z eff and N el experimental values showed good agreement with the theoretical values for calcined and sintered YBa 2 Cu 3 O 7Àd .
