Simultaneous Integral Measurement of Electron Energy and Charge Albedos

Electron energy and charge albedos were obtained for Be, Al, Ti, Mo, Ta, and U targets over the range of incident energies from 0.1 to 1.0 MeV. In the case of Al, Ta, and U the measurements were extended down to approximately 25 keV. Measurements were made for incident angles from 0° (normal) to 60°, and in some cases 75°, in 15° increments. The results agree well with existing experimental data and with Monte Carlo predictions, except at low energies where the discrepancies are only partially understood.
