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 {ital e}{sup +} on Au, and both {ital e}{sup {minus}} and {ital e}{sup +} incident on Al, evidence for specular scattering is observed. For positrons we find excellent agreement between these data and Monte Carlo simulations based on the Penn dielectric function.
