CeBr3 is emerging as one of the best scintillators having properties almost similar to Cerium doped lanthanum halide scintillators. We have measured, for the first time, the intrinsic energy resolution of Compton electrons in a cylindrical 1"x1" CeBr3 detector using the sources, namely, 137Cs, 22Na and 60Co employing Compton Coincidence Technique (CCT). We have used PIXIE-4 data acquisition system which makes the measurement setup quite compact. The results have shown that non-proportionality is the major factor in limiting the overall energy resolution of CeBr3 and the intrinsic resolution in CeBr3 arises due to processes other than the scattering of electrons inside the scintillator. We have also studied the dependence of intrinsic energy resolution on the coincidence window and optimized its value for a given source
