摘要:
Uranium total attenuation coefficients were measured continuously from 0.84 to 6.0 keV and at selected higher energies using a vacuum single crystal diffractometer and flow‐proportional counter. Statistical fluctuations ranged from 0.5% to 2%. The overall accuracy was 3%. Prominent structure was measured within 20 eV of theM5(3.552 keV) andM4(3.728 keV) edges. Jump ratios were determined from log‐log polynomial fits to data at energies apart from the near‐edge regions. These data were compared with calculations based on a relativistic HFS central potential model and with previously tabulated data.
