Description
A multi average-branch fit to the Inverse Beta Decay antineutrino spectrum recently measured by the Daya Bay collaboration with fine binning is performed to derive its corresponding electron spectrum. Utilizing the $^{235}$U to $^{239}$Pu electron spectrum ratio measured by Kopeikin et al., as well as the $^{235}$U to $^{238}$U and $^{241}$Pu electron spectra ratio from summation calculations, we are able to obtain the $^{235,238}$U and $^{239,241}$Pu electron spectra following their neutron induced fission under equilibrium condition, which are then compared with direct electron measurements. Following multi average-branch fits to these electron spectra, their corresponding IBD antineutrino spectra are obtained, which are compared to different measured and derived spectra.
