  I ran rdecay01 with attached macro : Eu152.txt
  The secondary spectrum are plotted by species : gamma.jpg  neutrino.jpg  electron.jpg
  On gamma.jpg you see peak at 780 keV is of the same order of the 960 keV 
  There is also a neutrino peak around 780 keV. Could be contribute to the overestimation ?
