Hello, I've got some questions about an experiment I did about the spectrum of a x-ray beam which I measured by looking at the diffraction off a NaCl crystal of the beam coming from a tungsten anode as a function of the scattering angle.
The measurement I got was something like the following picture

Now you can easily see three large peaks in this spectrum, which repeat themselves at higher angles but only with a lower intensity. Can I interpret these peaks as the diffraction maxima? You can also see that these peaks consist of two peaks very close to each other. Also the distance between those two peaks increases with each higher order diffraction. But I can't find a reason why this is true!
Ofcourse the x-ray beam has some penetration depth in the NaCl crystal, which is about 1 micrometer. Can I use this to correct the graph I made?
Thanks in advance,
Piet
