The aim of this work is to study the impact of the inclusion of the recently measured β decay properties of the {sup 102,104,105,106,107}Tc, {sup 105}Mo, and {sup 101}Nb nuclei in the calculation of the antineutrino (anti-ν) energy spectra arising after the fissions of the four main fissile isotopes {sup 235,238}U, and {sup 239,241}Pu in PWRs. These β feeding probabilities, measured using the Total Absorption Technique (TAS) at the JYFL facility of Jyvaskyla, have been found to play a major… Expand

New antineutrino energy spectra predictions from the summation of beta decay branches of the fission products.
It is concluded that new total absorption technique measurements are mandatory to improve the reliability of the predicted spectra of (235)U, (239,241)Pu, and, in particular, (238)U for which no measurement has been published yet. Expand

Indication of reactor ν(e) disappearance in the Double Chooz experiment.
The Double Chooz experiment presents an indication of reactor electron antineutrino disappearance consistent with neutrino oscillations, and an observed-to-predicted ratio of events of 0.944±0.016 and a deficit can be interpreted as a nonzero value of the still unmeasured neutrinos mixing parameter sin(2)2θ(13).
