Crystal – fixed orientation – beam of x-rays • 2 methods 1) Beams reflected back – called back reflection LT 2) reflected beam – pass through crystal t<1mm – transmission LT • 1 used – det orientation of lattice i/s crystals – are large, opaque to x rays • Prop’s vary – dirn i/s crystals • This study of anisotropic – knowledge of lattice orientation in crystals
