摘要：

We present new experimental results for the angle and energy resolved backscattering of positrons and electrons from Al and Au at oblique incident angles. For e+ incident on Au, and both e- and e+ incident on Al, evidence for specular scattering is observed. By contrast the e- scattering from Au is nearly symmetric about the surface normal. For positrons we find excellent agreement between these data and Monte Carlo simulations based on the Penn dielectric function.
