X-RAYS AND ORIENTATION OF QUARTZ CRYSTALS 



303 



TABLE I 



Quartz X-ray Reflection Angles 

 The Planes of Quartz from which the Cu Ka will reflect 

 d = Bragg angle of X-ray reflection for Cu Ka radiation 

 y = Angle that the plane normal A'^ makes with the Z axis 

 e = The angle between X and the plane containing the normal and Z, measured in the 



A' Y plane 

 / = Relative intensity of reflection
