This applet demonstrates how an incident X-ray beam intensity is reduced in various directions when hitting a spherically shaped crystal sample.
back to JAVA list
m = linear absorption coefficient [1/mm]
R = radius of the sphere [mm]
The red lines indicate which fraction of the
incident intensity is actually observable after passing the
With the scrollbar you may change the value of the product m*R within the range 0-2.5.
You may give some example value for the linear absorbtion coefficient in order to see which radius for the sphere would result.
The kernel of this applet is the table from International Tables Volume C , 1994, page 523, table 220.127.116.11. You may see that table when you look at the source code of this page!
