Anisotropy of attenuation revealed by angular intensity distribution of elastically backscattered electrons

► Electron attenuation investigated by directional elastic peak electron spectroscopy. ► Experimental and theoretical data obtained above LEED regime (0.6-1.8 keV). ► Anisotropic character of electron attenuation in mono-crystalline metallic samples. ► Extra decay in elastic channel due to elastic scatterings at larger angles.
