Class crw.solid.XrayTable 

java.lang.Object
   |
   +----crw.solid.XrayTable
public class XrayTable
extends Object
This class is a Hashtable contaning atomic symbol-XAtom pairs. This table provides all parameters necessary for calculating the atomic scattering factors (normal and anomalous dispersion). Most atoms needed for x-ray simulation of semiconductor cubic crystals are provided. The atomic scattering factors (ie., normal dispersion) are correct for sin(Theta)/lambda = 0.1 - 0.55. The Anomalous Dispersion values are correct for lambda = AgKa1 (0.55936A) - CrKa1 (2.28962A). For the x-rays, AgKa1, MoKa1, CuKa1, FeKa1, and CrKa1 the anomalous dispersion is 'almost' exactly in agreement with the International Table of X-ray Crystallography. For some atoms the anomalous dispersion parts may not be very accurate for the x-rays, CoKa1 and NiKa1.
