64-Gd-155 JEFF311N6434_0 C. Dean July 2009 The MeV/capture for Gd-155 in JEFF3.1(=JEFF-3.1.1) looks very wrong. The value in the file on record labelled 6434 3102 is 1.89MeV. The value in Mughabghab's atlas is 8.53639 +/- 0.00007 MeV. JEFF-β (Sublet) is using 8.536. Submitted

38-Sr- 92 JEFF311RDD_ALL Leconte 21 January 2011 The half-life of Sr-92 (2.71h) seems to be incorrect: recent studies over a measurement time of more than 10 radioactive periods have shown that the JEFF-3.1.1 half-life is overestimated by ~5%. A more accurate value has been deduced from the counting of the 1383.9 keV gamma-ray in Leconte et al., Appl. Rad. Isot. 66 (2008) 1450. A modified evaluation is proposed on the JEFF-β page.
