Q8)
Note its energy and provide an explanation for its existence
.
EC) 
Why would a characteristic X-ray from Al be harder to find than one from Pb?
 
 
Identification of Unknown Metal
 
Count and store a background run. Place the “unknown” metal sample under your counter and count for 
the same period of time.
Q9)
Note the appearance of an X-ray line in the subtracted spectrum.
Q10)
From the measurement of its energy, try to identify the “unknown” element. A good resource is the web 
site

http://Hyperphysics.phy
­
astr.gsu.edu/hbase/Tables/kxray.html
 
 
which derives its data from a comprehensive database maintained by NIST, the National Institute of Standards 
and Technology. The web site above will also list X-ray energy values for other elements such as Al, Ba, and 
Pb. With our apparatus, we won’t be able to distinguish between the two lines listed (corresponding to two 
closely spaced X-ray lines), since they are less than 1-2 keV apart for most elements.

The Report 
Your report should contain a brief description of the experiment. It should also contain an 
orderly
exposition of your measurements including computer printouts and graphs where appropriate. And of course, a 
summary table. Show examples of needed calculations and state clearly your conclusions: what did you 
measure? Did it agree with expectations? 
Extra credit:
Derive formula (6) from Eq 1-3. 
Derive (explaining as you go) formula (1); you’ll need relativistic particle kinematics. 
There are a number of possible Extra Credit measurements as well; ask your TA for suggestions.
