We measured the mean and FWHM for two lines which were identified by Reference ??? as being the result of fission events in cf-252
Pb-214
FWHM= 0.9 +/- 0.1 keV => = 0.39 +/- 0.043 keV
Max Energy shift = 23 keV
Tl-208
FWHM= 2.406 +/- 0.093 keV => = 1.02 +/- 0.39 keV
Predicted a Max Energy shift due to doppler effects of 172 keV
