DESCRIPTION:Speakers: V.  Guadilla (Univ. of Warsaw)\nIn this contribution
  we will present the study of beta decays of interest for reactor antineut
 rino\nspectrum calculations using the Total absorption gamma-ray spectrosc
 opy (TAGS). Measurements\nof the beta decays of several fission fragments 
 including 103\,108Tc\, 103\,108Mo and 95\,96Sr were done at\nthe Ion Guide
  Isotope Separator On-Line facility in Jyväskylä [1] using the Decay Tot
 al Absorption\ngamma-ray Spectrometer (DTAS) [2].\nThe complete beta inten
 sity distributions have been obtained based on the analysis approach\ndeve
 loped at IFIC [3\, 4\, 5] and they show that previous beta intensities det
 ermined with germanium\ndetectors were incomplete due to the Pandemonium e
 ffect [6]. In the present contribution we will\nstress the usefulness of a
  segmented spectrometer to evaluate the consistency of the results looking
 \nat the spectra with multiplicity conditions.\n[1] I. D. Moore et al.\, N
