Phone Meeting: HRS-R Carbon runs at th = 24deg. (01/30/2009)
Fitting of Carbon data
1.) 
2.) 
Fit for the elastic peak. To determine the number of counts in the elastic peak, I have integrated the peak
in the 4*sigma region around the position of the maximum.
3.) Fit for the 4.4MeV peak. To determine the number of counts in this peak, I have integrated the peak
in the 3*sigma region around the position of the maximum.
4.)
Fitted delta functions vs. Tiefenbach values
5.)
Problems with the carbon data
Additional peak appears in the momentum spectrum:
6.)
7.)
8.)
Determination of the cross-section
Number of counts in the elastic peak vs. collected charge:
9.)
Ratio: (Number of counts)/(Collected charge) prop. to. Cross_section
10.)
Two types of collimators were used in these runs:
1.) 1msr - collimator
2.) Smaller collimator (ellipsoidal) with additional holes on each side.
