Hey!
I'am doing a X-ray spectrometer lab, need some help regarding the absorption of x-rays by matter. one simple question, does material with higher atomic number stop more x-rays?
I have following measurement values:
no filter, 6k impulse rate/s
50 Sn, 111 impulse rate/s
30 Zn, 3173 impulse rate/s
29 Cu, 2735 impulse rate/s
28 Ni, 2829 impulse rate/s
the filters has the same thickness.
its kinda strange when Ni stop more x-ray compare to Zn, since Zn has bigger atomic number compare to Ni. But with Sn i can see a big absorption. can anyone give me a explanation?
thanks
