Spectra Analysis
According to the previous spectra obtained [1] FWHM for the lines in both gated and ungated gamma-spectrum from Cf-252 is around ~2 keV in the energy region from 0 to 2650 keV. However, theoretical calculation of the Doppler broadening shown that for example for energy 2617 keV it should be ~172.81 keV and 298 keV energy shift=19.7 keV.
As a conclusion, we can not see the Doppler broadening
